Yeah, this seems like a shoe-in for ES7. It will probably be able to advance through the stages very quickly given that it already has three (four?) shipping implementations.
Someone just needs to write up a formal spec (using Ecmarkdown! ^_^) and test262 tests. The only snag would be if you find non-interoperable behavior between browsers in the course of writing those tests, and need to get some patches accepted before you can reach stage 4.

In this case we'll be able to polyfill now, the spec'ing it will be trivial (I'll add the spec). I guess we just need to confirm it's good to go to ES7?

I use both lstrip() and rstrip() in Bikeshed (a Python project): https://github.com/tabatkins/bikeshed/search?utf8=%E2%9C%93&q=lstrip&type=Code https://github.com/tabatkins/bikeshed/search?utf8=%E2%9C%93&q=rstrip&type=Code In particular, lstrip() is used when I'm separating a key and value; I don't want to mess with the value much at all, just pull off the whitespace at the start. rstrip() is used when I know I don't need to strip from the left side, because I'm just pulling off newlines or something, so might as well let the program avoid even trying. ~TJ
