enumstep: enumerate with integrated pause command

Hello

After having used prosper and now partially switching to texpower, I
realized that there is one environment I really miss from prosper.

Enumstep: there automatically the pdf file advance with every item.

So I thought of defining me something similar, I tried:

\newenvironment{enumstep}{\begin{enumerate}{{\pause}}
{\end{enumerate}}

Which did not work.

Maybe somebody already has come up with something.
Seems a feature worth to implement, anyhow.

Thanks
