your form confuses me a lot, because it's not clear to me where 'y' and
'z' are coming from. what if the thing returned by fn() doesn't have a
'y', is it going to pull 'y' from the lexical scope, or is it going to
use 'undefined' for 'y'?
the es-harmony form
var {x: a, y: b} = fn();
makes intuitive sense to me because the thing on the left is a
pattern-matching template. I'm saying that I expect the rhs object to
have that shape, and if the shape does match, pull out values from it.
