removed shorthand sample

@Russ: heh, sorry I think we're just saying the same thing. You're right, jQuery simply does var toString = Object.prototype.toString;. My point was Object.prototype.toString !== window.toString, which invalidates your statement that the second example is equivalent to the first example, that's all :) Cheers.

FYI the second example is not a valid shorthand. jQuery creates a local toString reference that simply points to Object.prototype.toString.
