Yeah I'm thinking that even if I had such a function, it might be impossible
to make it play nicely. I think I can do a restricted form of what I want
with STRefs and StableNames (still dangerous) so I think I'll stick with
that at least while experimenting in haskell.
DCC looks extremely interesting! In fact it looks like I can do what I'm
wanting out of the box!
I will definitely have to experiment with it :)
