You'll need to cast the value, but you can guard this cast

I never get these is-expressions right on first try, but the
idea should be clear.
You don't have to use an explicit cast. Enum values can be
implicitly converted to their base enum type:
---
string str = E.one;
writeln(str); // prints "1"

If DMD pull request #1356[1] is pulled, I think we'll be able to
do:
---
writeln(string(E.one)); // prints "1"

I recommend avoiding the cast operator whenever possible.
