[Python-Dev] Update PEP 7 to require curly braces in C (original) (raw)

I'm usually fine with code like this:

 if ( ... )
     return

But when there is a multi-line 'else' clause, I just want to use braces for both 'if' and its 'else'. So, for consistency, I'm +1 for recommending to use braces everywhere.

And +1 for requiring to use braces if one of the clauses of the 'if' statement is multi-line.

While doing a review of http://bugs.python.org/review/26129/ I asked to have curly braces put around all if statement bodies. 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?
