I would argue that the behavior of lib/complex.rb be considered a bug
because the existing method is overridden but the existing method's
behavior is changed incompatibly. Bugs can be fixed in patchlevels.

OTOH, while 1.8.8 is not well defined (at least I don't know where to
look for a definition), it could be the target for this change. Of the
two options, I'd really like to see it changed in 1.8.7.

Cheers,
