I hope it's not (1): I want the language I use to include more "batteries" not fewer. <petpeeve>It seems that a similar "simplicity argument" was invoked to strip the cmp option from sort in Python 3. Grrrr. Simplicity is great, but when the drive for it starts causing useful functionality to be thrown out, then it is going too far. Yes, I know that it is possible to do everything that sort's cmp option does through clever tricks with key, but grokking and coding this maneuver requires a *lot* more Python-fu than cmp did, which makes this functionality a lot less accessible to beginners that the intrinsic complexity of the problem warrants. And for what? To get rid of an *option* that could be easily disregarded by anyone who found it too "complex"? It makes no sense to me.</petpeeve> -- http://mail.python.org/mailman/listinfo/python-list
