Right, hence the idea to use the compile-time overloading and automatic
conversions. op_add() would be defined only for two Ints returning an Int and
for two Refs returning a Ref. Then if something else like "two Ints returning
a Ref" is needed, the C++ compiler will use the (Int, Int) version and convert
the result from Int to Ref automatically. If something unsatisfiable is
needed, like (Ref, Ref -> Int), then it means that there is a problem with the

I should have saved some intermediate results, but I wasn't on Internet so I
couldn't just check in my progress and now it's really in the middle of a
rewrite... Give me some more time...
