I'm currently working on subclassing built-in types, but redefining
operations for existing built-in types is not part of my agenda, for
various reasons (most of which have to do with boring implementation
details, but are real showstoppers nevertheless).

So alas, no relief from that angle.  Maybe we'll have to accept a
directive.
