Detailed Description

Performs typed closure conversion.

This is based on the Simply Typed Closure Conversion. Closures are represented using tuples: [Env: *, Cn [Env, Args..], Env]. In general only continuations are converted. Different kind of Lams may be rewritten differently:

• returning continuations ("functions"), join-points and branches are fully closure converted.
• return continuations are not closure converted.
• first-class continuations get a "dummy" closure, they still have free variables.

This pass relies on ClosConvPrep to introduce annotations for these cases.

Note: Since direct-style Defs are not rewritten, this can lead to problems with certain Axms: ax : (B : *, int -> B) -> (int -> B) won't be converted, possible arguments may. Further, there is no machinery to handle free variables in a Lams type; this may lead to problems with polymorphic functions.
