a 'self' reference may resolve the issue,

What about how JavaScript does it.  Anonymous functions can still have a
"name" that can be used from inside of a function to refer to itself.

And the most useless example ever.

var f = function func ( i ) {
    return func(7);
};

I think that this is nice because there is no name space pollution, no new
keywords needed and it is pretty.
