Thank you, that's what I thought, but then I started adding them 
and there was no warning and I was like "wait... is this 
top-down???"

Okay again makes more sense. The amount of stuff that was "kinda" 
working, plus learning through tiny 3 liner code snippets in 
docs, was making my brain explode a bit.

A constructor/factory pattern for this makes way more sense.

functional, verses procedural/linear.
