I want to modify the enumerate environment (from enumitem) to always be passed a certain optional argument. I expected the following code to work, but it always stalls (takes forever).
\documentclass{article}
\usepackage{enumitem}
\let\ooenumerate\enumerate
\let\endooenumerate\endenumerate
\renewenvironment{enumerate}[1][]{%
\ooenumerate[series=test,#1]%
}{
\endooenumerate%
}
\begin{document}
\begin{enumerate}
\item ione
\end{enumerate}
\end{document}
I'm on
