If Python ever adopts the BCPL rule for implicit line continuation if the last thing on a line is an operator (or if there's an open parentheses), then the break-after-an-operator rule would be more persuasive. ;)
[IIRC, the BCPL rule was that there was an implicit continuation if the grammar would not allow inserting a semicolon at the end of the line, which covered both the open-parens and last-item-is-operator cases, and probably a few others.] But I should shut up and leave shut discussions to python-ideas.
