[Hauke Tschach]

Hi,

if in the following code the "\rbkt" is replaced by just "]",
latex fails to produce a dvi file.

Hauke




\documentclass{article}

\newcommand{\rbkt}{]}

\begin{document}

\begin{description}
  \item[$a[a\rbkt$] here the problem arrises:  just $]$ does not work.
\end{description}

\end{document}
