I find this a bit disingenuous. Each time assignment as an expression comes up, so that it would be possible to have an assignment in a if or while condition, few of the regulars seem to have a problem with the argument that the current choice protects against a particular kind of bug. The fact that braces protect against a kind of bug you care less about, is just your preference. That doesn't mean a different preference is somehow worthy of ridicule. Mistakes of all kinds happen and I see no reason to ridicule someone for wishing protect against one kind of mistake, while yourself having the protection you like. -- Antoon Pardon -- https://mail.python.org/mailman/listinfo/python-list
