I think he means that the GC from the standard lib will still be there
to perform that .dup for you.
(You don't need the dup though, btw, string literals are null
terminated and can be passed to C funcs as-is).

Even without that, the GC doesn't get eliminated from executables just
because you don't use it.
There's still some hidden calls to gc init routines that go into any D exe.
