           Summary: "this" object in methods called on primitives should be
                    wrapper object
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mjs at apple.com


In cases like this:

String.prototype.thisType = function() { return typeof this; };
Number.prototype.thisType = function() { return typeof this; };
Boolean.prototype.thisType = function() { return typeof this; };

shouldBe("(1).thisType()", "'object'");
shouldBe("(2.3).thisType()", "'object'");
shouldBe("'xxx'.thisType()", "'object'");
shouldBe("(false).thisType()", "'object'");

We're currently providing the raw number or string or bool as the "this" value,
which is subtly wrong.
