Dynamic languages have a few features in common:
- Very weak typing with lots of automatic conversion.
- Oddball control flow

Will there be haskell on parrot? How easy/hard would that be?
Just curious, Richard
I've no idea, but the GHC team recently changed their backend from gcc
to c--, so maybe that has potential?
It would certainly be interesting to see how interopability is handled.
