In fairness, the same could be said about any() and all() in the first
place. The advantages are that the built-ins are significantly faster
than the pure-Python version (a factor of 3 times faster on my machine
using Python 3.1), and they're available everywhere you go, without
re-writing the functions or importing them.
I'm (mildly) with Bruce on this one, but I think we missed the boat.
Perhaps in Python4000 any() and all() should return the relevant object
rather than True/False.
