Description

The Boo compiler needs to treat generator methods that return a generic parameter or an open constructed type differently, and generate a generic generator return type rather than a concrete one.

Example of generic generator method yielding a generic parameter (this won't compile):

import System.Collections.Generic 

def YieldStuff of T (items as IEnumerable of T):  
  for item in items: yield item

Can't create a generic generator type until creation of generic types is supported.

Closing as we can actually compile this now (and emit it), but the invalid IL is invalid => BOO-759
