String methods have been a net gain, I think.
garbage collection is a CPython implementation detail, not a language property (it's a nice implementation detail, sure). and we had iterators before we got the iterator protocol; the protocol made things slightly more convenient, but it didn't enable you to do anything you couldn't do before (using __getitem__ instead of __next__). generators are something entirely different. writing inverted code is hard; yielding is trivial. func(*arg) instead of apply() is a step back -- it hides the fact that functions are objects, and it confuses the heck out of both C/C++ programmers and Python programmers that understand the "def func(*arg)" form, because it looks like something it isn't (there's a false symmetry between the call-form and the def-form). and I still do enough 1.5.2-programming to use "x = x + y"; when I find myself in a situation where my code would benefit a lot from being able to write "x += y" instead, I go back and fix the design. string methods are nice, but nothing groundbreaking, and their niceness is almost entirely offset by the horrid "".join(seq) construct that keeps popping up when people take the "the string module is deprecated" yada yada too seriously. and what do the python-devers do? they add a "sum" built-in, but no "join"? hello? </F> -- http://mail.python.org/mailman/listinfo/python-list
