    That said, if you go for functional style in OOP, i.e. 
    shoving as much as you can into static helper functions and
    most of the rest into dumb private stateless functions,

We had this at a company I worked at a while back - dozens of modules with nothing but static functions that all took a first argument of the same type. If only there was some kind of METHOD for declaring a whole bunch of functions that operated on the same data...

Until you get into polymorphism etc. this is just a style thing.

method(a,b) is equivalent to a.method(b) and exactly as much typing. You do save manually typing the extra part of the definition but 'eh'. A few languages treat these interchangeably.
