When using func-names = never, allow names for recursive use

What version of ESLint are you using? 2.13.0

What parser (default, Babel-ESLint, etc.) are you using? default

Please show your full configuration: "func-names": [2, "never"]

The problem you want to solve I would like to never use function names, because in Mozilla code the names in stacks are guessed pretty well nowadays. There are some cases where I still need them though, namely when referencing the function name within for a recursive call.

Example:

setTimeout(function postpone() {
    let thing = getThing();
    if (!thing) {
        setTimeout(postpone, 0);
    } else {
        complete();
    }
}, 0);

Your take on the correct solution to problem. I would suggest to add an keyword option recursive or similar, setting it to true would allow use of function names if referenced from within. The default should be true.

Right now func-names is either “always” or “never”. What about making it “always/recursive/never”? That would be a non-breaking enhancement and avoid a boolean object option.

I’m working on this.
