[ES7] Basic support for async functions/methods

I use them in many projects notably for class methods because the syntax prevents me from easily using workarounds such as Bluebird.coroutine(function * generator() {}). Unfortunately doing so breaks parsing and prevents EsLint from finding other errors.

I understand that fully implementing async functions could be a lot of work and that it is not a priority to support ES7 features for now but a preliminary support such as simply removing them from the source would at least allows the parsing of the rest of the code.

@benjamine This issue is a bit out-of-date; if you’re using ESLint 3.6.0 or higher, you can now use parserOptions: {ecmaVersion: 8} in your config to enable async/await.

Want this too. 😢 Currently I use babel-eslint which isn’t a good solution - eslint parses transpiled code which I didn’t write and catches errors in that.
