%%% Setting a higher cache version will cause a re-evaluation of the

%% \DeclareCachedDocumentCommand is now just a plain wrapper around \DeclareDocumentCommand
|
|
%% that implements this caching, so it is not useful on itself
|
|
%%
|
|
%% If \DeclareCachedDocumentCommand is, however, some macro that does lengthy computations
|
|
%% and then issues one ore more of underlying \DeclareDocumentCommands
|
|
%% we can save this computation on the second run, since we do not evaluate
|
|
%% \DeclareCachedDocumentCommand further (we just copied its definition)
|
|
%% and load the plain definitions that the invocation produced in the last run
|
|
%% and that we saved to the aux file for restoration.
