You clone it from github (git clone URL listed at top) and run the
code one form at a time in core.clj; or, just copy the code in
core.clj from the code browser on github itself.

In Clojure 1.3, BigInts are said to be contagious across operations.
When different types of numbers are used in a math operation, the
result will be the larger or more general of the two types. For
example, any integer operation involving a BigInt will result in a
BigInt, [...].

You have discovered a very recent change. The idea is to automatically
switch to longs for performance when it is clear that overflow will
not occur.

There are still some problems with this optimization,
Thanks, Eric. My original problem was the factorial function, which
breaks despite using BigInts:
user= (defn fact [n] (if (= n 1N) 1N (* n (fact (- n 1N)
#'user/fact
user= (type (fact 1))
clojure.lang.BigInt
user= (type (fact 20))
java.lang.Long
user= (type (fact 21))

Right, this feature is documented in
http://dev.clojure.org/display/doc/Documentation+for+1.3+Numerics
For me it feels somewhat strange to use primed operations to enforce
upgrade casting and to write a special faculty function for that.

Why not opencl? This way you would be able to run the code in any
hardware and even a hybrid approach cpu+gpu(AMD and NVIDIA), you could
even think about webcl (javascript to access the gpu) which I think
has some form of GC. Besides, opencl code is very similar to CUDA
code.
Whatever you do,
I haven't looked at aparapi [1] in detail, but it seems interesting

Yes if we were going for a very simple OpenCL in Clojure Syntax, the

the correct way to *change* to a namespace is in-ns. Calling ns will also
refer to clojure.core. The first scenario happens because the namespace
already exists and the ns tries to refer extend to #'clojure.core/extend
