Hi again.
Is there some preferred style for referring to a family of function
variants? For example, from xpeek:
% \begin{macro}[aux]{\@@_if_in:NNTF}
% \begin{arguments}
% \item Token-list to search through (the “haystack”)
% \item Token to search for (the “needle”)
% \end{arguments}
% Among the \cs{tl_if_in:**\textit{TF}} conditionals
% defined in \pkg{expl3}, \cs{tl_if_in:NNTF} is missing.
% But since that’s the functionality I need, define it:
% \begin{macrocode}
Is “\tl_if_in:**TF” (with or without “TF” being italicized) a
recognizable, non-ambiguous way to refer to those functions as a set,
or is there a nomenclature already in use that I should rather adopt?
