There shouldn't (afaik) be a problem with nested function calls; the problem
is where the definition of a function appears inside the definition of
another; indeed if you nest a function definition inside another you can't
call the container function more than once (because it will attempt to
redefine the nexted function on the second call and fail).
Recursive functions, used properly, are a Good Thing [tm].
