Obviously you need to google the definition of "spaghetti code". When
you move code out of one function and create another function you are
contributing to the "spaghetti-ness" of the code. Think of plate of
spaghetti and how the noodles are all intertwined and without order.
Likewise when you go to one function and have to follow the trial of
one or more helper functions you are creating a twisting and unordered
progression of code -- sniff-sniff, do you smell what i smell?

Furthermore: If you are moving code out of one function to ONLY be
called by that ONE function then you are a bad programmer and should
have your editor taken away for six months. You should ONLY create
more func/methods if those func/methods will be called from two or
more places in the code. The very essence of func/meths is the fact
that they are reusable.

It might still be spaghetti under that definition (of which ALL OOP
code actually is!) however it will be as elegant as spaghetti can be.

Which is it? You cannot have it both ways. You're straddling the fence
here like a dirty politician. Yes, this subject IS black and white!
