+% \section{Using boxes efficiently}
+%
+% The functions above for using box contents work in exactly the same
+% way as for any other \pkg{expl3} variable. However, for efficiency
+% reasons, it is also useful to have functions which \emph{drop} box
+% contents on use. When a box is dropped, the box becomes empty at the group
+% level \emph{where the box was originally set} rather than necessarily
+% \emph{at the current group level}. For example, with
+% \begin{verbatim}
+% \hbox_set:Nn \l_tmpa_box { A }
+% \group_begin:
+% \hbox_set:Nn \l_tmpa_box { B }
+% \group_begin:
+% \box_use_drop:N \l_tmpa_box
+% \group_end:
+% \box_show:N \l_tmpa_box
+% \group_end:
+% \box_show:N \l_tmpa_box
+% \end{verbatim}
+% the first use of \cs{box_show:N} will show an entirely cleared (void) box, and the
+% second will show the letter |A| in the box.
+%
+% These functions should be preferred when the content of the box is no
+% longer required after use. Note that due to the unusual scoping behaviour of
+% \texttt{drop} functions they may be applied to both local and global boxes:
+% the latter will naturally be set and thus cleared at a global level.

-% The standard solution is to use an \texttt{x}-expanding assignment
-% and set \tn{everyeof} to \cs{exp_not:N} to suppress the error at
-% the end of the file. Since the rescanned tokens should not be
-% expanded, they are taken as a delimited argument of an
-% auxiliary which wraps them in \cs{exp_not:n} (in fact
-% \cs{exp_not:o}, as there is a \cs{prg_do_nothing:} to avoid losing
-% braces). The delimiter cannot appear within the rescanned token
-% list because it contains twice the same character, with different
-% catcodes.
-%
-% The difference between single-line and multiple-line files
-% complicates the story, as explained below.
+% A related minor issue is a warning due to opening a group before the
+% \tn{scantokens} and closing it inside that temporary file; we avoid
+% that by setting \tn{tracingnesting}. The standard solution to the
+% ``File ended'' error is to grab the rescanned tokens as a delimited
+% argument of an auxiliary, here \cs{@@_set_rescan:NNw}, that performs
+% the assignment, then let \TeX{} ``execute'' the end of file marker.
+% As usual in delimited arguments we use \cs{prg_do_nothing:} to avoid
+% stripping an outer set braces: this is removed by using
+% \texttt{o}-expanding assignments. The delimiter cannot appear
+% within the rescanned token list because it contains twice the same
+% character, with different catcodes.
+%
+% For \cs{tl_rescan:nn} we cannot simply call \cs{@@_set_rescan:NNnn}
+% \cs{prg_do_nothing:} \cs{use:n} because that would leave the
+% end-of-file marker \emph{after} the result of rescanning. If that
+% rescanned result is code that looks further in the input stream for
+% arguments, it would break.
+%
+% The two \cs{if_false:} \ldots{} \cs{fi:} are there to prevent
+% alignment tabs to cause a change of tabular cell while rescanning.
