Here, I'm torn. I do want the code to be accessible to non-stats
people
Essentially, I'm looking for a Python equivalent to the ObjectiveC stuff that
can be found at:
http://developer.apple.com/documentation/UserExperience/Conceptual/AddressBook/index.html
Google got me that far, but was not particularly helpful past that.
Anyone have any pointers?

I think I'd probably prefer:
def cons(a,b):
res = [a]
res.extend(b)
return res
because cons is supposed to leave its second argument untouched.
