This is the body of swap for simple types:

   auto tmp = lhs;
   lhs = rhs;
   rhs = tmp;

For more complex types:

   ubyte[T.sizeof] t = void;
   auto a = (cast(ubyte*) &lhs)[0 .. T.sizeof];
   auto b = (cast(ubyte*) &rhs)[0 .. T.sizeof];
   t[] = a[];
   a[] = b[];
   b[] = t[];

So yeah. If that's not inlined, something's wrong.
