I understood both the iterative version (which was efficient)
and the "naive" recursive version MUCH better than the "efficient"
recursive version.

Being able to write the efficient recursive version proves you're
smart, which is very important to some people.  Being able to
write the efficient iterative version proves you don't have to be.

Since I write code to solve problems, not prove my intellectual
prowess, my vote goes for the "dumb" solution.  Probably this
is why I use Python.

Sorry. ;-)
