I'd like to point out that there is already my patch for that, which implements set comprehensions and list comprehensions exactly as syntactic sugar for GEs. This, however, affects performance greatly as LCs are executed in their own function scope, which isn't necessary. A better implementation would therefore leave the LC implementation as is, only preventing the name leaking into the enclosing scope.

Do you think you have it in you to tackle this?
