Is there a mechanism that allows you to loop over all of an
enum's values? I've wanted to do so a couple times now for
CTFE/mixin templates.

I was able to loop over the underlying type when my enum was
integer-based, but I can't do that if the values are strings
(also that solution is quite hacky).

Perhaps there's a pattern involving __traits?

__traits(allMembers) on the enum can do it or this can help too http://dlang.org/phobos/std_traits.html#EnumMembers

Brilliant! Thanks Adam! I actually checked your book before any
other sources for this :)
