1. I can't tell when the { x y } inside the local is supposed to shadow
the outer x and y.

2. How are you supposed know when the quotation's lifetime has ended, if
you've passed the xt to some other word that might have saved it
somewhere?  Normally that's implemented with garbage collected closures,
but I don't think that's what you're describing.
