-% \subsection{Patching definitions to deprecate}
-%
-% \begin{quote}
-% \cs{__kernel_patch_deprecation:nnNNpn} \Arg{date} \Arg{replacement}
-% \meta{definition} \meta{function} \meta{parameters} \Arg{code}
-% \end{quote}
-% defines the \meta{function} to produce a warning and run its
-% \meta{code}, or to produce an error and not run any \meta{code},
-% depending on the \pkg{expl3} date.
-% \begin{itemize}
-% \item If the \pkg{expl3} date is less than the \meta{date} (plus
-% $6$~months in case \texttt{undo-recent-deprecations} is used) then
-% we define the \meta{function} to produce a warning and run its code.
-% The warning is actually suppressed in two cases:
-% \begin{itemize}
-% \item if neither \texttt{undo-recent-deprecations} nor
-% \texttt{enable-debug} are in effect we may be in an end-user's
-% document so it is suppressed;
-% \item if the command is expandable then we cannot produce a warning.
-% \end{itemize}
-% \item Otherwise, we define the \meta{function} to produce an error.
-% \end{itemize}
-% In both cases we additionally make \cs{debug_on:n} |{deprecation}|
-% turn the \meta{function} into an \tn{outer} error, and
-% \cs{debug_off:n} |{deprecation}| restore whatever the behaviour was
-% without \cs{debug_on:n} |{deprecation}|.
-%
-% In later sections we use the \pkg{l3doc} key \texttt{deprecated} with
-% a date equal to that \meta{date} plus $6$~months, so that \pkg{l3doc}
-% will complain if we forget to remove the stale \meta{parameters} and
-% \Arg{code}.
-%
-% In the explanations below, \meta{definition} \meta{function}
-% \meta{parameters} \Arg{code} or assignments that only differ in the
-% scope of the \meta{definition} will be called \enquote{the standard
-% definition}.
-%
-% \begin{macro}
-% {
-% \__kernel_patch_deprecation:nnNNpn, \@@_patch_aux:nnNNnn,
-% \@@_warn_once:nnNnn,
-% \@@_patch_aux:Nn,
-% \@@_just_error:nnNN
-% }
-% (The parameter text is grabbed using |#5#|.) The arguments of
-% \cs{__kernel_deprecation_code:nn} are run upon \cs{debug_on:n}
-% |{deprecation}| and \cs{debug_off:n} |{deprecation}|, respectively.
-% In both scenarios we the \meta{function} may be \tn{outer} so we
-% undefine it with \cs{tex_let:D} before redefining it, with
-% \cs{__kernel_deprecation_error:Nnn} or with some code added shortly.

-% \end{macrocode}
-% In case we want a warning, the \meta{function} is defined to produce
-% such a warning without grabbing any argument, then redefine itself
-% to the standard definition that the \meta{function} should have,
-% with arguments, and call that definition. The \texttt{e}-type
-% expansion and \cs{exp_not:n} avoid needing to double the~|#|, which
-% we could not do anyways. We then deal with the code for
-% \cs{debug_off:n} |{deprecation}|: presumably someone doing that does
-% not need the warning so we simply do the standard definition.

-% \meta{parameters} \Arg{code}, so |#1#2| performs the assignment.
