The reason you are getting “never used” message is because you actually haven’t
used foo anywhere. You declared it, and you set a value for it, but you haven’t
read it anywhere or done anything with it. Try the following code in a demo and
it’s not going to throw any errors:
/*global foo: true */
/*eslint no-console: 0*/
/*eslint-env browser*/
foo = 5;
console.log(foo);

Subject: [ESLint] "never used" error on used global
Reproducible in the demo, at http://eslint.org/demo/
Enter this:
/*global foo: true */
foo = 5;
w/o the global directive, eslint throws "foo undefined". With global true, it
throws "never used". With global false it throws "foo is read only".
Is this a bug?
