No, not in 0.7. The code hasn't been committed to our CVS archive yet,
so it won't be in the betas. It will probably be in the next release,
(it will probably be in the betas in about a month, if all goes smoothly).
It will take a while for it to become stable, however, and we're likely
to want to redesign some of the library around typeclasses.
