Intent to ship: ES6 generator functions (V8)

[Andy Wingo]

[FYI +blink-dev]

ES6 defines a new language feature, "generator functions" [1].

ES6 generator functions have been shipping in Firefox since version 26
(December 2013) [2]. Although IE and Safari developers participated
actively in the design of generator functions, and so we expect
generator functions to be implemented by them, we don't know when.

V8 has had generator functions since June 2013, under the
--harmony-generators flag. The specification has undegone minor changes
since then, to which we have adapted. To our knowledge, the V8
implementation of generators is specification-compliant, with a few
known bugs that will be fixed [3]. Work to nicely integrate generator
objects with devtools is ongoing [4].

Thank you for sharing! Exciting, I know a lot of developers have been waiting for it. Hopefully Internet Explorer and Safari implements them soon enough as well.

Do you intend to ship it with the referenced issues, or is the plan to fix them before shipping (preferred, obviously)?

The answer is different for the different bugs. Some will be fixed,
some will take more time. We consider the incompatibility impact of
fixing them to be low enough that it's reasonable to ship already.

This may also make some library devs happy (link as an example)
