It's always been string, and should always be.

But I don't know of another case where it returns something that can't 
be passed to getMember. You should be able to use getMember on "std", 
and then getMember on that with "stdio". Just like any other nested thing.

It would be just as confusing as if you had:

struct S
    int foo;

and __traits(allMembers, mod) contained "".

BTW, when I wrote that first response, I didn't realize that 
__traits(allMembers, std) returns... a lot of stuff. the whole mechanism 
seems like it doesn't do what I would expect.
