I think this PEP is very relating to language design philosophy.

(a) Overload operator heavily for convenience.

(b) Prefer methods over operators. Set a high bar for overloading operators on core types.

I prefer (b) philosophy. And I don't think described usefulness is enough for adding the operator.

I know this is a subjective opinion, but I'm -1 on this PEP.

Equally subjective, of course, but I prefer to be able to use operators. There's a good reason that we use mathematical symbols for non-numeric data types already (adding tuples together, multiplying a list by an integer, etc), and it definitely makes code easier to read. +1. ChrisA
