[docs] [issue12188] PEP 7, C style: add ++ policy and explanation

Ezio Melotti <ezio.melotti@gmail.com> added the comment: I'm not sure it's worth adding this to the PEP 7. The PEP is about conventions and style not idioms. PEP 8 has a section about "Programming Recommendations" that contains a few idioms, but since PEP 7 doesn't have an equivalent section, I think that explaining this idiom (and not others) will look out of place. ---------- nosy: +ezio.melotti _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue12188> _______________________________________
