Can iterators be reset in Python?
... one crucial warning in the docs for it:
This itertool may require significant
auxiliary storage (depending on how

to use list() instead of t...

return function () {
window.clearTimeout(timer);

Is there a built in function for string natural sort?
....isdigit() else text.lower()
for text in _nsre.split(s)]
Now this function can be used as a key in any function that uses it, like list.sort, sorted, max, etc.
As a lambda:
lambda s: [int(t) if t.isdigit() else t.lower() for t in re.split('(\d+)', s)]
