__traits[1] is your friend in these matters.

__traits( allMembers, Foo ) returns a tuple of string literals, each of
which corresponds to a member of Foo.

If you prefer the temmplated way, here's a FieldNameTuple template:

template FieldNameTuple( T ) {
     enum FieldNameTuple = __traits( allMembers, T );
}

Somehting I discovered today: it works for module names, also:

auto ioMembers = __traits(allMembers, std.stdio);

It also contains the unittests... Hmm, I wonder what one can do with that.
