You may be right -- this has been discussed many, many times before. In my personal opinion, the best (and only accurate!) phrase would have been: for item in sequence: # block then: # block ​IMO, for item in sequence: # block nobreak: # or perhaps if not break: # block would be clearer (if the syntax is necessary at all).

You couldn't have "if not break:" because that would look like the start of an 'if' statement.

"nobreak" would introduce a new keyword, but "not break" wouldn't.
