Sorry, that's wrong.

Like Pit just suggested elsewhere in this thread, we can't override to
log (a, :plus, b) then a._oldplus_(b).

The design is short-circuited ... *not* optimized.

A language designer shouldn't test her abilities to second guess what
the user is likely to want or need to do. It's a lost cause. :)
