Only if you're using an inferior compiler. A good compiler should
recognize Unchecked_Conversion and use it to treat the data at
whatever address as an object of whatever type. It shouldn't generate
a copy or any other code.
Check the code your compiler is producing. If it's generating code to
copy the object, call your compiler vendor and bawl them out for
stupidity. :-) (Don't mind me, I'm in an intolerant mood today.)
