Not sure if I understood the question correctly, but the way I 
understood it:

1) To iterate over a specific part of a non-random-access range, 
you can use `drop` in conjunction with `take` or `takeExactly`.

2) To get an existing foreach loop to emit a range, move its body 
to the predicate of `map`, and break conditions to the predicate 
of `until` / `countUntil`.

3) As I understand, "get the beggining of this range until the 
first x, without slicing" is what `until` (or `countUntil` + 
`take`) does.
