no-unused-var exception when destructuring?

In the code below (es6), eslint throws an no-unused-var error on the _ argument:

   return this._getProperties()
      .filter(([ prop ]) => prop.isDirty())
      .map(([ _, propName ]) => propName);

When destructuring, it is a common to use _ to denote variables that won’t be used. Would there a way for eslint to ignore those kinds of unused variables?

See https://github.com/airbnb/javascript/issues/435

eslint v0.24.1

Reopen this? It’s still an issue IMO.

var [,,, w] = produce_vector()

is not as clear code as

var [ _x, _y, _z, w] = produce_vector()

when you want to clearly see that w is indeed w.

that’s “args ignore pattern”; wouldn’t a destructuring need a “vars ignore pattern”? Also I think if you enable the ignoreRestSiblings option it will work.
