But the scope of the answers is just one computation, so what should it
save? Consider:
asksign(x);
Is x p, n, or z? p
=> p
asksign(x);
Is x p, n, or z? n
=> p
This would have to be changed to something like
(assume(x>0), temp: asksign(x), forget(x>0), temp) => p
(assume(x<0), temp: asksign(x), forget(x<0), temp) => n
What's more, it is perfectly legal and reasonable for user code to make
assumptions dynamically....
