We can add it since its stage 4.

I'm not sure what Acorn's policy is on ES7 yet.

@nzakas Thank you very much for acornjs/acorn#382!

relevant eslint issue

Any chance this could make it in, so that it can make it up to eslint? ES7 is a-comin!

Only blocker was waiting on an Acorn release, and that just happened, so it can make its way soon. (I need to add some exponentiation operator tests to Espree to validate the token output.)

[ljharb]

Yay, thanks!

I took a quick look at this. Unfortunately, Acorn has several breaking changes that makes this a more involved upgrade than I expected. :(

[nzakas]

I found a bug in Acorn's implementation, so blocked on that now: acornjs/acorn#384

[nzakas]

The Acorn bug has been fixed, just waiting for a new release.

[ljharb]

yay, Acorn has released v3.0.4
