A very interesting read! I wouldn't support some of the more exotic
elements tacked on to the end (particularly the replacement of the now
thoroughly entrenched bitwise operators), but the basic idea of
providing ~op variants of several operators seems fairly sound. I'd be
somewhat inclined to add ~not, ~and and ~or to the list even though
that would pretty much force the semantics to be elementwise for the ~
variants (since the standard not, and and or are always objectwise and
without PEP 335 there's no way for an object to change that).
