No, everything would be in a scalar context. If you used tie() to
specially tie a variable, then you might be able to overload +, *, -,
etc, but this is no different from overloading other objects, which you
can do currently.

There are already well-established precedence rules on operator
overloading; check out the Camel-3 chapter on it. The methods proposed
in RFC 159 would follow these same rules, although this should probably
be explicitly stated in the RFC.
