__proto__ breaks abstraction boundaries in the language -- it's just
Hiding for the sake abstraction is more valuable than introspective visibility? I disagree, at least with JavaScript, IMHO JS's introspective nature is one of it's greatest strengths. Is there a precedence for this in other languages? Java is big on abstractions but inheritance is still introspectable (I realize that is not completely the same). And I believe that Self, the closest relative, makes the proto available throught .parent* property (I could be wrong about that). security threat depends on the details of the environment: whether Hasn't that security threat been evaluated by the years that this property has already been available?
