Yes I have read it. It's difficult to formulate the question in English bu I'l try. In this example I searching for special symbols '&' and '='. So when symbol found I use *save* method of range to remember start of *name* or *value* string of URL encoded param. Then I trying to find next special symbol. And when I found it I need to take a slice and insert in result AA. Should input range be RandomAccess for it? And if it's not random access range should should I append this substring by symbol to some temp variable and then (when delimiter found) insert into Associative Array. So result is that I will implement two different behaviours for InputRange and for RandomAccessRange. Am I right or not?

If you want to be able to *slice*, then you need an `RandomAccessRange` with `hasSlicing`.

a RandomAccessRange is a special kind of ForwardRange, which itself is an Input Range.
