sorry, Kangax for the delay in getting back to you. My computer turned
off before I could click send last night.
Of course, we can return named function.
What I'd want to avoid, however, (for measurable[1] performance hit
_every time the function is called_) is multiple closures.
So we should be avoiding the following construct:
(function() {
var index = 1;
return (function() {
if (SOME_FEATURE_TEST) {
return function namedFunc() { return index }
}
return function namedFunc2() { return index + 1 }
})();
})()
