I'm not sure I understand what you mean, Ryan.
JavaScript doesn't have a notion of "static" (except for a reserved
keyword that's not even implemented). There are "direct" members and
members shared via object's [[Prototype]]. Since prototype.js
simulates "classes" a reasonable definition of static would be:
properties of a Function object created via Class.create. The way
Antoine put it sounds confusing to me (and I'm sure to other folks as
well)

Doesn't really matter how we call it : )
Having bunch of logic in constructor is not a good design (in my
experience)

It's obviously a matter of priorities. For me, performance is usually
one of the key factors. Simulating "private" properties (in a highly
dynamic language) does not compensate for the decreased speed.
