Not a bad idea. The FFI can still introduce aliasing, though I don't know if that matters. Alignment is still a problem though. Plus it's a bit more complexity, though an optimizer should be able to do something about that. I'll see how much work an implementation would be. Andy -- http://wingolog.org/
