Wishes for enum in future builds

[GRiN]

When the enum inherients a type it would be nice not to have to do a cast to
that type.
enum MyEnum: int{one=1,two=2}
MyEnum Mine = 1; // no error!

It would be nice to constrain an enum to a function call (makes code easier
to read, and prevents bad calls)
public int MyRouting(enum inEnum{one=1, two=2} ){ return (int)inEnum;}
int i = MyRoutine(one); // enum would only have scope in routine and calls
to routine

It *doesn't* inherit from a type though.
enum MyEnum: int{one=1,two=2}
MyEnum Mine = 1; // no error!
Please no! That reduces the type safety of it. The whole point of enums
are that they're separate types.

Looks like a bit of a readability-killer to me. If you need an enum,
make it a proper type.

For my wishlist on enums, however, see
