Memoize is certainly a readily approachable example.

But the factorial example on the wiki has a defect.  It incorrectly
calculates factorial(0) as 0, when it should be 1.  I don't know how
to edit the "inline" code in the wiki, but if someone out there knows
how, consider changing:

    if n < 2:
        return n

to:

    if n < 2:
        return 1

Have a nice day!
