Serhiy pointed out that PEP 7 says curly braces are optional: https://www.python.org/dev/peps/pep-0007/#id5. I would like to change that. My argument is to require them to prevent bugs like the one Apple made with OpenSSL about two years ago: https://www.imperialviolet.org/2014/02/22/applebug.html. Skipping the curly braces is purely an aesthetic thing while leaving them out can lead to actual bugs. Anyone object if I update PEP 7 to remove the optionality of curly braces in PEP 7?

Though I don't write C anymore, I occasionally read our C sources. I dislike mixed bracketing in a multiple clause if/else statement, and would strongly recommend against that. On the other hand, to my Python-trained eye, brackets for one line clauses are just noise. +-0.

If coverity's scan does not flag the sort of misleading bug bait formatting that at least partly prompted this thread

if (a): b; c;

then I think we should find or write something that does and run it over existing code as well as patches.
