async shorthand functions cause parsing errors if they are named 'delete' or 'import'

[Standard8]

Using ESLint, with Espree 3.5.0, we are seeing failures that we were not seeing with 3.4.3.

Example failure:

var foo = {
  async import() {
  }
}

With 3.5.0 this fails with Parsing error: Unexpected token import

Downgrading to 3.4.3 or changing the name of the function to something else, e.g. bar passes.

We've also seen that async delete() {} causes a similar issue.

I suspect this is a regression from #341 given the release notes.

Thank you for this issue.

This has been fixed already on the master branch of upstream: acornjs/acorn#584.
Please wait for the next patch release of acorn, then re-install it.

Unfortunately updating acorn isn't enough as espree seems to be overriding this issue. I've just created #353 with the fix ported across.

Oops, I'm sorry, I had forgotten that.

I'm just wondering if there is a likely ETA for when the fix for this could be included in a release?

Currently I'm trying to resolve a few issues with dependencies in one of the modules I'm working on for Firefox, but I'm hitting up against this issue at the moment. Having an ETA would be useful for knowing when I can get back to fixing it.

Thanks.

We had been planning to release it along with the scheduled ESLint release next week.

If there's someone waiting on the fix we might be able to do it sooner though.

@not-an-aardvark Next week is fine, it'll be good timing for us.
