Doesn't reduce return a non-list (or at least, isn't it the case that
it doesn't necessarily return a list the way map and filter do)?
An *abuse* of a list comprehension, or a list comprehension in
conjuction with something else, could probably replicate reduce(),
but why bother? reduce() isn't really like map and filter.
