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?
