For compatibility with other ECMAScript engines, `Object.prototype.__defineGetter__` must behave as described here: http://mathias.html5.org/specs/javascript/#object.prototype.__definegetter__ JavaScriptCore has a minor bug where it throws a SyntaxError instead of a TypeError in cases like the following: var object = {}; object.__defineGetter__('foo', '_'); Online tests: http://mathias.html5.org/tests/javascript/object/

So obvious I forgot to mention it, but the same goes for `Object.prototype.__defineSetter__`.

Yup - syntax errors should all be early errors, doesn't sounds appropriate here. We should make this a type error. Thanks for the bug report!
