           Summary: Object.prototype.__defineGetter__ with non-callable
                    second parameter should throw TypeError instead of
                    SyntaxError
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://mathias.html5.org/specs/javascript/#object.prot
                    otype.__definegetter__
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mathias at qiwi.be

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', '_');
