Why are the parentheses irritated? Have you been taunting them? :)

Yes please!

I'll bet most people who play with ASTs want this, build something half-assed, never finish it, and lose it by the next time they look at ASTs again three years later... So if you finish something, that'll save effort for hundreds of people in the future (who have no idea they'll want it one day).
