EventEmitter.listener() returns different function then that one registered

[Flarna]

If I register a listener using once() and then read the listener array using listeners() I would expect to get an array with one entry pointing to my listener.
But actually listeners(eventName)[0].listener is actually pointing to my function as EventEmitter wrapped my listener for the once handling.

If I register a listener using on() then listeners(eventName)[0] points to my listener.

Is this intended?

Some people have seen it as a bug, there was a PR at the core repository that would have fixed it: nodejs/node#5564

That proposal got a bit lost because there was another PR that did a similar thing, but only for the 'removeListener' event, not .listeners(). I think it would be fair to open a issue at https://github.com/nodejs/node/issues so that, at the very least, this problem does not get lost. Care to do that? :)
