Well... the main problem is not with the '+=' operators themselves, it's with the 'global coherence'. I would assume then, that if the '+=' operator is assumed to modify objects in-place, it would just fail on immutable objects, wouldn't I? I mean... I don't like that. I'm not really a Python expert, I found this behaviour is documented in the language reference itself: http://docs.python.org/ref/augassign.html But... I don't know, still think it's confusing and not going to use it. -- Alan Franzoni <[EMAIL PROTECTED]> - Togli .xyz dalla mia email per contattarmi.
