[MLton-devel] Int.precision is 32 bits?

Interesting. People I've talked always pulls the expansion argument
when the polymorphic->monomorphic problem is solved by instantiation. On
the other hand boxing and coercions or RTTI seems to be quite slow
compared to instantiation. 

But it does also mean that using a polymorphic function in MLton is as
fast as using a type annotated one, or am I wrong here?
