-% Leaves in the input stream the items from the \meta{start index} to the
-% \meta{end index} inclusive. Spaces and braces are preserved between
-% the items returned (but never at either end of the list).
-%
-% Here \meta{start index} and \meta{end index} should be integer denotations.
-% For describing in detail the functions' behavior, let $m$ and $n$ be the start
-% and end index respectively. If either is $0$, the result is empty. A positive
-% index means `start counting from the left end', a negative index means
-% `start counting from the right end'. Let $l$ be the count of the token list.
-%
-% The \emph{actual start point} is determined as $M=m$ if~$m>0$ and as $M=l+m+1$
-% if~$m<0$. Similarly the \emph{actual end point} is $N=n$ if~$n>0$ and $N=l+n+1$
-% if~$n<0$. If $M>N$, the result is empty. Otherwise it consists of all items from
-% position $M$ to position $N$ inclusive; for the purpose of this rule, we can
-% imagine that the token list extends at infinity on either side, with void items
-% at positions $s$ for $s\le0$ or $s>l$.
-
-% Spaces in between items in the actual range are preserved. Spaces at either end
-% of the token list will be removed anyway (think to the token list being passed to
-% |\tl_trim_spaces:n| to begin with.
-%
-% Thus, with $l=7$ as in the examples below, all of the following are equivalent
-% and result in the whole token list

-% \iow_term:x { \tl_range:nnn { abcd{e{}}fg } { -6 } { -3 } }
-% \end{verbatim}
-% are all equivalent and will print |bcd{e{}}| on the terminal; similarly
-% \begin{verbatim}
-% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { 2 } { 5 } }
-% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { 2 } { -3 } }
-% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { -6 } { 5 } }
-% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { -6 } { -3 } }
-% \end{verbatim}
-% are all equivalent and will print |bcd {e{}}| on the
-% terminal (note the space in the middle). To the contrary,
-% \begin{verbatim}
-% \tl_range:nnn { abcd~{e{}}f } { 2 } { 4 }
-% \end{verbatim}
-% will discard the space after `d`.
-%
-% If we want to get the items from the third to the last, the call
-% is |\tl_range:nnn { <tl> } { 3 } { -1 }|. Similarly, for discarding
-% the last item, we can do |\tl_range:nnn { <tl> } { 1 } { -2 }|.

+% {\tl_range:Nnn, \tl_range:nnn}
+% \begin{syntax}
+% \cs{tl_range:Nnn} \meta{tl~var} \Arg{start index} \Arg{end index}
+% \cs{tl_range:nnn} \Arg{token list} \Arg{start index} \Arg{end index}
+% \end{syntax}
+% Leaves in the input stream the items from the \meta{start index} to the
+% \meta{end index} inclusive. Spaces and braces are preserved between
+% the items returned (but never at either end of the list).
+%
+% Here \meta{start index} and \meta{end index} should be integer denotations.
+% For describing in detail the functions' behavior, let $m$ and $n$ be the start
+% and end index respectively. If either is $0$, the result is empty. A positive
+% index means `start counting from the left end', a negative index means
+% `start counting from the right end'. Let $l$ be the count of the token list.
+%
+% The \emph{actual start point} is determined as $M=m$ if~$m>0$ and as $M=l+m+1$
+% if~$m<0$. Similarly the \emph{actual end point} is $N=n$ if~$n>0$ and $N=l+n+1$
+% if~$n<0$. If $M>N$, the result is empty. Otherwise it consists of all items from
+% position $M$ to position $N$ inclusive; for the purpose of this rule, we can
+% imagine that the token list extends at infinity on either side, with void items
+% at positions $s$ for $s\le0$ or $s>l$.
+%
+% Spaces in between items in the actual range are preserved. Spaces at either end
+% of the token list will be removed anyway (think to the token list being passed to
+% |\tl_trim_spaces:n| to begin with.
+%
+% Thus, with $l=7$ as in the examples below, all of the following are equivalent
+% and result in the whole token list
+% \begin{verbatim}
+% \tl_range:nnn { abcd~{e{}}fg } { 1 } { 7 }
+% \tl_range:nnn { abcd~{e{}}fg } { 1 } { 12 }
+% \tl_range:nnn { abcd~{e{}}fg } { -7 } { 7 }
+% \tl_range:nnn { abcd~{e{}}fg } { -12 } { 7 }
+% \end{verbatim}
+% Here are some more interesting examples. The calls
+% \begin{verbatim}
+% \iow_term:x { \tl_range:nnn { abcd{e{}}fg } { 2 } { 5 } }
+% \iow_term:x { \tl_range:nnn { abcd{e{}}fg } { 2 } { -3 } }
+% \iow_term:x { \tl_range:nnn { abcd{e{}}fg } { -6 } { 5 } }
+% \iow_term:x { \tl_range:nnn { abcd{e{}}fg } { -6 } { -3 } }
+% \end{verbatim}
+% are all equivalent and will print |bcd{e{}}| on the terminal; similarly
+% \begin{verbatim}
+% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { 2 } { 5 } }
+% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { 2 } { -3 } }
+% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { -6 } { 5 } }
+% \iow_term:x { \tl_range:nnn { abcd~{e{}}fg } { -6 } { -3 } }
+% \end{verbatim}
+% are all equivalent and will print |bcd {e{}}| on the
+% terminal (note the space in the middle). To the contrary,
+% \begin{verbatim}
+% \tl_range:nnn { abcd~{e{}}f } { 2 } { 4 }
+% \end{verbatim}
+% will discard the space after `d`.
+%
+% If we want to get the items from the third to the last, the call
+% is |\tl_range:nnn { <tl> } { 3 } { -1 }|. Similarly, for discarding
+% the last item, we can do |\tl_range:nnn { <tl> } { 1 } { -2 }|.
+%
+% The behavior of \cs{tl_range:Nnn} is exactly the same, acting on the
+% contents of the tl variable.
+%
+% For improved performance, see \cs{tl_range_braced:nnn} and
+% \cs{tl_range_unbraced:nnn}.
+% \begin{texnote}
+% The result is returned within the \tn{unexpanded}
+% primitive (\cs{exp_not:n}), which means that the \meta{item}
+% does not expand further when appearing in an \texttt{x}-type
+% argument expansion.

+% To avoid checking for the end of the token list at every step, start
+% by counting the number $l$ of items and \enquote{normalizing} the
+% bounds, namely clamping them to the interval $[0,l]$ and dealing
+% with negative indices. More precisely, \cs{@@_range_items:nnNn}
+% receives the number of items to skip at the beginning of the token
+% list, the index of the last item to keep, a function which is either
+% \cs{@@_range:w} or the token list itself. If nothing should be kept,
+% leave |{}|: this stops the \texttt{f}-expansion of \cs{tl_head:f} and that
+% function produces an empty result. Otherwise, repeatedly call
+% \cs{@@_range_skip:w} to delete |#1| items from the input stream (the
+% extra brace group avoids an off-by-one shift). For the braced
+% version \cs{@@_range_braced:w} sets up
+% \cs{@@_range_collect_braced:w} which stores items one by one in an
+% argument after the semicolon. Depending on the first token of the tail,
+% either just move it (if it is a space) or also decrement the number of
+% items left to find. Eventually, the result is a brace group followed by
+% the rest of the token list, and \cs{tl_head:f} cleans up and gives the
+% result in \cs{exp_not:n}.
