# Starred equivalent in newenvironment

Let's say I want to use the align-environment in a newenvironment like this:

\newenvironment{mequation}{\align}{\endalign}

This works fine. However, what if I want to use the starred version of align*?

\newenvironment{mequation}{\align*}{\endalign*}

Doesn't seem to work.. Any ideas?

I expect there is a simple xparse solution to this: defining a starred and non-starred version at the same time... –  Seamus Mar 21 '11 at 18:52
