 Description   

See the Typed Racket implementation. Poly-fresh* is only needed when checking a plambda.

ambrosebs: why is Poly-fresh: needed in the plambda type checking code, but nowhere else?
asumu: ambrosebs: that's the only place where the body of the lambda is checked.
asumu: The only purpose of Poly-fresh is to make sure the references to the bound type variable in the body are resolved in the correct way.
asumu: When the type is just manipulated otherwise, it doesn't matter.
