Please read the pep first: the proposal is already for multichar
operators, and the various alternatives are discussed in detail there.
 The .OP form is specifically addressed in the pep, so if you want to
discuss that one, you need to cover the objections to it already
raised in the pep.

As I said before, this discussion shouldn't start from a blank slate:
consider the pep 225


as the starting point that python-dev will want for any useful discussion.
