a reflection on if and how "this" is used inside a function, would reveal what inner-interface it uses to some object, also also if it mutates its properties. every function mutating this-bound objects is potentiallyt a cinstructor. afaik:
new Foo(); is aequivalent to Foo.call(Object.create(Foo.prototype)) with an implicit "return this" at Foo"s end.
