Error with generator method with a symbol name

[julien-f]

standard prints indx.js:0:0: Cannot read property 'toString' of undefined with the following code:

console.log(class {
  * [Symbol.iterator] () {}
})

There are no errors if is an object literal instead of a class:

console.log({
  * [Symbol.iterator] () {}
})

And if the computed property name is not a symbol but a plain string I get the incorrect but different error message 2:12: Expected spaces around *.:

console.log(class {
  * ['foo'] () {}
})

The first issue is already reported to ESpree (eslint/espree#123) but not the second one.

Can you also report the second issue to eslint/espree? That's the right place for it. It's a dependency of a dependecy for standard ;-).

After investigation it seems it simply does not work with methods in classes.

Anyways, the generator-star is deprecated in favor of generator-star-spacing (which also has an issue with generator methods but is more likely to get fixed − eslint/eslint#2351).

I delete deprecated rules from the .eslintrc whenever we bump the eslint version.
