TypeScript support for ES Next pipeline operator

Don't they still have to wait for the spec to finalize / hit stage 3?

Don't get me wrong, I'm super excited for this functionality because I love it in languages like F# and Elixir, but it looks like the pipe proposal is still stage 1.

While I think this is a risky move, I had the impression that the ratification of new features was mainly based on the implementations.

So, first the runtimes/compilers implement it and then it gets into the spec.

TypeScript sees itself as a superset of ECMAScript, so its ECMAScript parts are just another implementation of the spec, like Node, Babel and the browser engines.

Yes, this appears to be just a tracking issue, not an impending implementation (and definitely not a PR). The "Waiting for TC39" label added even has the tooltip "Unactionable until TC39 reaches some conclusion".

Livescript (which was supposed to replace CoffeeScript) also has it.
