html.HTMLParser, json.JSONDecoder, re.compile, tokenize.tokenize don't

Common use case is quickly find substring starting from current
position using str.find or re.search, process found token, advance
position and repeat.
For that kind of thing, you don't need an actual character
index, just some way of referring to a place in a string.
Of course. But _existing_ Python interfaces all work with indices. And
it is too late to change this, this train was gone 20 years ago.
There is no need in yet one way to do string operations. One obvious way
is enough.
