I didn't know this would work for 'and/or' operators (even I've read the
style guide PEP!), sorry. It's not super beautiful, but I could live
happy with that :)

I never said that commas should mean line continuation (as a backslash).
It CAN be used as implicit line continuations in lot cases, (like
function arguments, for instance. This would be just one more case.
