RSplit, RFind in standard library

[nihil]

Do you consider to add RSplit, RFind (like Python has) and other similar functions to standard library?

See https://golang.org/pkg/strings/

They're not named RWhatever, though. I think that's a feature.

From Python docs about rsplit: Except for splitting from the right, rsplit() behaves like split()

I didn't find anything similar in strings.

Okay, maybe we don't have things "from the right". I don't think that's useful enough for the standard library.

nihil, strings.LastIndex is the equivalent of Python's rfind. You're right that there's no equivalent of RSplit.

The strings package has suffix or from-the-right versions of almost every anchored operation other than SplitN. It seems almost inconsistent to *not* have a SplitLastN.

I personally find strings.RFind to be a better name than strings.LastIndex.
