Very well argued and explained. I will have to chew on that a bit. Perhaps
I'll keep moving on the road towards minimalism. :)

It's essentially a `filter` or `select` function, except that it returns
two lists (tables in Lua): the list of items that match a predicate - as
with `filter` - and a second list of items that don't match. (Makes for an
easy way to split a list into two groups and then hand the results over to
different functions for processing.)
