compiler adds enclosing $this to all inner class ctors

Since every non-static nested class (i.e. inner class) needs a never-null pointer to the enclosing OBJECT (I don't mean "class"), java compiler actually adds an implicit arg to every inner class ctor. The type of the arg is the enclosing CLASS (I am not saying "object")

Note this is all compile time.
