I wrote it because I got sick of Assert(false) debugging, and I was chasing
down some "ERROR: 08P01: insufficient data left in message" errors. Then I
got kind of caught up in it... you know how it is.
It also goes to show there are plenty of places you might want to get a
stack where you don't have an internal errcode or panic. I don't think that
idea will fly.
