[plt-scheme] schemeregion in an environment

Is it possible to use schemeregion inside another environment (like
itemize)?  The slatex manual suggests that it is, but it doesn't seem
to work for me.  I thought this program would work:

\documentclass{article}
\usepackage{slatex}
\begin{document}

\begin{schemeregion}
  \begin{itemize}
    \item
      \begin{schemeprogram}
        stuff
      \end{schemeprogram}
  \end{itemize}
\end{schemeregion}

\end{document}

but it gives an error about a missing \item.
