Of course, this means that the minusminus operator is now part of the
language and must be supported in the future.

It is also difficult to understand your motivation for making the ++
operator right-associative. What prevents a compiler from implementing
(X ++ Y) ++ Z as "first concatenate Y and Z, then concatenate X with
the result"?
