I think you are binding ':' here too tightly to the 'for' construct in your mind. The for construct is "for <variable(s)> in <sequence>" which can be used as <block construct>:<statement(s)> in block constructs. The above is not a block construct but a list comprehension so it follows different rules. -- D'Arcy J.M.
