Title: Add Enum.each/1

Not sure if this will actually be taken or not since there is currently a bit of debate about it going on on IRC, but here it is in any case.

This is useful for forcing the realization of lazy enumerables (like
Streams!) without building a list such as would be the case if one used
Enum.to_list.
