I've been away for a week, but inf is "undirected infinity" then are the two
Symbols, each inf, the SAME? If not, then inf*inf might be -inf.
Whatever that means.
Like intervals, [-1,1] * [-1,1] ... Is it the same interval or two different
objects that happen to have the same description.
I haven't read through all the messages on inf though..
