We've been discussing this recently, but haven't made any announcement -
we hope to release Mercury 0.7 in the next few weeks. 

If you can't wait...

There are untested betas at
the latest of those (4th of July) certainly has (some) support for
functor and arg. But this support is incomplete (higher order types and
module qualification are definite problems), and the release is
not necessarily very stable.
