Ada requires that scalars be passed by copy. I was under the impression
that this was chosen because it was faster, but i've never seen a 
rational argument for this from the Ada83 perspective of computer
hardware, nor whether such arguments still hold true for modern 
processors.

Can anyone shed any light on this?
