Summary: Python should have a unary division operator (a.k.a.
reciprocal), written "/x", analogous to unary subtraction (a.k.a.
negation), written "-x". And then "~x" should be what is intended by
Python, namely bitwise negation.
Rationale: Mark Bell gave a talk at Sage Days 74 and he mentioned this
as a problem. His software (flipper) uses bitwise negation (the ~
operator) a lot and that breaks when using Sage Integers, where ~ means
reciprocal.
Given that Python does not have a reciprocal operator, this problem
cannot really be fixed. So if we want operators both for bitwise
negation and reciprocal, we need to add a new operator to Python.
I have no idea how feasible it is to actually get a new feature accepted
by Python, but it makes a lot of sense to me and the numpy people pulled
it off for the matrix multiplication @ operator.
