Allow nested Enumerables #4
Description
Allow using an Enumerable as the type of an Enumerable. Currently this is not possible since the Enumerable struct does not implement comparable and there does not seem to be a way to do this now. The current implementation is restricted to comparable types to allow for methods like Contains and TakeWhile. If it were possible to switch on the generic type we may be able to allow this. Some proposals are currently open for the language spec. This seems to be a current shortcoming of generics in general.
