+% the next line as the a continuation of the current line, you can use a single
+% backslash as it's done here:

+% \pagestyle{empty}

+%  {x.z -> |42|} \
+%  \text{\sffamily R1}
+% \end{phiquation*}
+% \end{document}
+% \end{docshot}
+
+% The |phiquation| environment may be used together with \href{https://ctan.org/pkg/acmart}{acmart}:
+% \begin{docshot}
+% \documentclass{acmart}
+% \usepackage{eolang}
+% \thispagestyle{empty}

-%   Normal tokens are not too hard, but can be \tn{outer}, hence the
-%   \cs{exp_not:N} in the code above.  If the token is expandable then
-%   it might be an \tn{outer} or a \TeX{} conditional, so to be safe we
-%   set it to \cs{scan_stop:} (the assignment is local and stopped by
-%   the \cs{group_end:} upon calling the user's code).  Then distinguish
-%   characters (including active ones and macro parameter characters)
-%   from control sequences (whose string representation is more than one
-%   character because the escape character is printable).  For a control
-%   sequence call the user code with suitable arguments.
+%   Expandable tokens (which are automatically |N|-type) can be
+%   \tn{outer} macros, hence the need for \cs{exp_after:wN} and
+%   \cs{exp_not:N} in the code above, which allows the next function to
+%   safely grab the token as an argument.  We run some code that is
+%   expanded using the primitive \cs{cs_set_nopar:Npx} rather than
+%   \cs{tl_set:Nx} to avoid grabbing it as an argument as |#1| may be
+%   \tn{outer}.  To allow~|#1| as an argument of the user's function
+%   (stored in \cs{l_@@_peek_code_tl}), we set it equal to
+%   \cs{scan_stop:}, but we do it at the last minute because |#1|
+%   may be some pretty important function such as \cs{exp_after:wN}.
+%   Then we put the user's function and the elaborate first argument
+%   \cs{__kernel_exp_not:w} \cs{exp_after:wN} |{| \cs{exp_not:N} |#1| |}|:
+%   indeed we cannot use \cs{exp_not:n} |{#1}| as this breaks for an
+%   \tn{outer} macro and we cannot use \cs{exp_not:N} |#1|, as
+%   \texttt{o}-expanding this yields a \enquote{notexpanded} token equal
+%   to (a weird) \tn{relax}, which would have the wrong value for
+%   primitive \TeX{} conditionals such as \cs{if_meaning:w}.
+%
+%   Then we must add |{-1}0| if the token is a
+%   control sequence and \Arg{charcode}|D| otherwise.  Distinguishing
+%   the two cases is easy: since we have made the escape character
+%   printable, \cs{token_to_str:N} gives at least two characters for a
+%   control sequence versus a single one for an active character
+%   (possibly being a space).  Producing the right outcome is trickier,
+%   as |#1| cannot appear in either branch of the conditional (it could
+%   be \tn{outer}, or simply a \TeX{} conditional), and can only be
+%   safely discarded by \cs{use_none:n} if it is first hit with
+%   \cs{exp_not:N}.

+%   For normal characters we must determine their catcode.  The main
+%   difficulty is that the character may be an active character
+%   masquerading as (i.e., set equal to) itself with a different
+%   catcode.  Two approaches based on \tn{lowercase} can detect this.
+%   One could make an active character with the same catcode as~|#1| and
+%   change its definition before testing the catcode of~|#1|, but in
+%   some Unicode engine this fills up the hash table uselessly.
+%   Instead, we lowercase~|#1| itself, changing its character code
+%   to~$32$, namely space (because \LuaTeX{} cannot turn catcode~$10$
+%   characters to anything else than character code~$32$), then we apply
+%   \cs{@@_analysis_b_char:Nn}, which detects active characters by
+%   comparing them to \cs{tex_undefined:D}, and we must have undefined
+%   the active space for this test to work ---we use an |x|-expanding
+%   assignment to get the active space in the right place.  Finally
+%   \cs{@@_peek_analysis_char:w} puts the arguments in the correct
+%   order, including \cs{exp_not:n} for macro parameter characters and
