In what other language you have direct access to methods as first class objects to do an immediate execution of a method returned by an execution container (parenthesis in JS) ?

I think most people would write it like this:

    playing ? player.play() : player.pause()

Not sure if i understand the question. This seems to work in Python:

    s = "Hello"
    up = True
    (s.upper if up else s.lower)()
Not that it's a very pythonic piece of code, but it works, and i would expect many other languages support something similar.

Anyway, that's tangential. And i wasn't discussion what "most people would" do either. What i was trying to say is that by aliasing "var self = this" you're not automatically immune to the quirks of "this" in JS.
