Isn't that sort of like saying "complex reals" (sic) are a
kind of real number. ;)
And you forgot "Omnific Integers" ... :)
http://mathworld.wolfram.com/OmnificInteger.html
But I am inclined to agree with Leopold Kronecker:
http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Kronecker.htm
l
"... he believed in the reduction of all mathematics to
arguments involving only the integers and a finite number
of steps. Kronecker is well known for his remark:-
God created the integers, all else is the work of man.
Kronecker believed that mathematics should deal only with finite
numbers and with a finite number of operations. He was the first
to doubt the significance of non-constructive existence proofs."
(With that attitude, surely Kronecker should be counted among
the fathers of modern computer algebra. ;)
So therefore I prefer to think that there is really only one
kind of Integer.

I am willing to bet on it. In fact I am seriously considering
how we could make the source immediately available under a
provisional license. See the thread on the axiom-legal list.

Really, Aldor is "nearly" open source already. All you have to
do to get access to the source code is to ask at aldor.org.
Practically speaking, this means obtaining the approval of
Steven Watt. So far as I know, no one who has asked has ever
been denied access.
