           Summary: Delegates should be allowed as foreach aggregates

Seeing as how foreach works on objects by calling a method with a certain
signature, it should be feasible to allow delegates with that same signature as
the aggregate.  This would provide a clear selective iteration concept, and
with the use of delegate literals and delegates to nested functions, could
possibly lead to a number of new design patterns.
