I wanted to try using OOHaskell as a library, but I've run into some
problems I don't understand.

Nice work! I haven't tried it out, but you
yeah, that is what I mean. however, since we don't have explicit type
passing in haskell, reasoning about the lazyness of types would be quite
tricky, leading to odd things like changing type signatures (without
changing the underlying types) can change the behavior of a program.

Concerning the point someone made about the features of Haskell:
* pattern matching: just case distinction

These are indeed local syntactic issues but the amount of such small things
