> Though neither python nor rust have such a nice `.split(None)` built in.

Sorry, I'm not sure I understand what `.split(None)` would do? My initial instinct is that would would return each character. i.e. `.chars()` in Rust or `list(s)` in Python.

Reading the docs [0] it seems `.split(None)` returns an array of the indivual characters without whitespace - so something like [c in list(s) if not whitespace(c)]

It was intended to split a list of `int|None` into its non-none stretches. Much like how `string.split('x')` splits a string by matching the character 'x'

Gotcha! In python there is a `split_at` function for this in the more-itertools package, but I don't think there is a concise way to do it in the stdlib.
