I wouldn't. In the case of true pass-by-copy, all calls (no matter what the 
arguments) pass-by-copy. In the case you're talking about, you are passing 
by-reference, but some calls pass-by-copy. (Janus/Ada 83 used this technique 
a lot for generics, as pass-by-copy allowed one to change representations as 
needed; it's cheaper than using reading and writing thunks (which we have to 
do in Janus/Ada 95, because of the possibility of aliased components)).
