It depends on what exactly you're trying to do.  Some time ago, I wrote
a library that created XML loaders for structs, and it needed to know
the names of fields.  Pre-traits, this is what I used:

struct Stuff
{
    int foo;
    char[] bar;

    alias Tuple!("foo", "bar") _fields;
}

Then I just looped over _fields.
