global use of counter commands such as \alph* to access the current counter.

[davidcarlisle]

Brief outline of the enhancement

enumitem has popularised using \arabic* and similar in item labels to access the current list counter. This feature isn't yet available in the latex-lab list module but the addition of \@currentcounter to the format back in 2020 makes it possible for these commands to be globally available, not just in item labels. So for example \roman* (really \roman{*}) would access the current counter as used by \label and typeset it in roman.

It could have a trivial definition, as shown below,

\documentclass{article}
\makeatletter
\protected\ExpandArgs{c}\def{c@*}{\value\@currentcounter}
\makeatother

\begin{document}

\section{aaa}
\arabic*

\subsection{bb}
\subsection{bbb}

\arabic*


\begin{enumerate}
\item \arabic*
\end{enumerate}
\end{document}
