Was generating functions based on free type variables, not on the kind
of the constructor.

c140d690fc First draft of cross-module type checking 
Currently, all top-level types are imported. No alias resolution
happens so you need to use "import open M" atm.

807076ad57 Add CSaveEnv, optimize CAnd, make it prettier 
CSaveEnv is a special constraint that indicates that the current
environment should be saved for later use.

(/\) now optimizes away arguments that are already CTrue.

through the same mechanism. Need to test further.
