[issue32915] Running Python 2 with -3 flag doesn't complain about cmp/__cmp__

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

The stated goal of -3 is "warn about Python 3.x incompatibilities that 2to3 cannot trivially fix", so this use case seems like a good match.

On the other hand, adding this to -3 would be somewhat noisy since __cmp__ is pervasive in 2.7.
