I recently tried compiling enumap with GDC, and found that it 
disagrees with DMD on whether a function is @nogc. Here's a 
semi-reduced test-case:

Here's an @nogc version of `byKeyValue()`:

@nogc auto byKeyValue() const {
  static immutable keys = [EnumMembers!K];
  return zip(keys[], _store[]);
}

Using zip and slices guarantees that the structure returned will 
be only 5*size_t.sizeof bytes, regardless of the types of K and V.
