Somewhere in your module ?-)

(snip)

If your problem is to reduce the apparent complexity of the method, 
defining the function inside the method won't help that much (unless the 
function by itself is short enough - and event then...). Apart from 
having a direct access to the method's namespace, you don't gain much by 
doing so. And if it's a an implementation function that doesn't need to 
access the instance, it has no reason to be a method. Moreover, since 
it's not part of neither the class or the module interface, you can 
freely change your mind if and when you find a need to do so.
