Yes, I understand that. What I'm really after at this point is
that I would like to write a clever mixin that would handle all
of these decisions for me. It should generate a function that
takes arguments and returns the result by value or const
reference depending on what is more appropriate for the given
types. I was under the impression that this could be accomplished
using in or some other qualifiers.
