I think adding even more intrinsics to the compiler is really not an option.
The system unit is already overcrowded and bloated with intrinsics,
so adding even more for what is at best a real corner case:
I really don't think that's a good idea.
If speed matters so much to some people, don't use setlength(), use getmem().
