Actually unchecked conversion can cause copies, which are more easily
avoided with address overlays. 

I can imagine no technical justification for your claim that UC is
safer, let alone infinitely safer, than address overlays. I suspect
this is just a hold over from Ada 83 thinking, with no good technical
justification.
