I don't see this, though. Don't oversell!
I think it's true: you can't do this with private name.
private filter;
Object.filter = function defaultFilter() { ... };
[0, 1, 2].filter(...) // will triggers Object.filter and not Array.filter,
because filter is not "filter" anymore but a private name instead.
If you use a "normal name" with a reduced visibility instead, the classical
prototype chain will continue to works as expected.
