Well, remember, i want the table because right now i have to take a
use, and walk the entire def chain backwards, to get the default def's
version.
This is expensive.
Out of curiosity, why do you need the default def? ie, why do you care
that a_2 is live on entry when you have a_4 = a_3 + 2, and a_3 has a
def?
