If you post to python-ideas, you'll probably be told to gather feedback
here first. The core-developers aren't hugely interested in arbitrary new
features unless they have significant community support.
I've never needed such a split function, and I don't like the name, and
the functionality isn't general enough. I'd prefer something which splits
the input sequence into as many sublists as necessary, according to the
output of the key function. Something like itertools.groupby(), except it
runs through the entire sequence and collates all the elements with
identical keys.
E.g.:
splitby(range(10), lambda n: n%3)
=> [ (0, [0, 3, 6, 9]),
(1, [1, 4, 7]),
(2, [2, 5, 8]) ]
Your split() would be nearly equivalent to this with a key function that
returns a Boolean.
