Ok, I missed your point, as for the second example it was an attempt 
to show that further refactoring from a function with local functions
that are sharing some state via the scope object, to a class with
methods that share state via the instance, is a matter of editing
a few lines.  

This is useful when a function grows too large (for some value of 
"too large"). As an added bonus you get to use the same thechniques
with both styles of coding.
