Hi Alessio, John,

Just a quick response, since I'm at work:

It is indeed a bug. It's fall-out from the change Mark Evenson
committed to catch unmatched Go and Return exceptions. I committed a
change yesterday which should prevent that type of exception
(unmatched, that is) to ever happen. I'll check his change and revert
the bit which causes these control errors.

That's true.

We're looking for someone (or funding so I can quit my day-job :-) to
implement d-m-c. It's been one of the things we deerly want to
implement but which exceeds the time and effort available at the
moment. Hence we're addressing other issues, such as performance,

Hope that explains some.
