js_GetArgument used to be

JSBool js_GetArgument(JSContext *cx, JSObject *obj, jsval id, jsval *vp)
{
    JSFunction *fun;
    JSStackFrame *fp;

    fun = (JSFunction *)JS_GetInstancePrivate(cx, obj, &js_FunctionClass,
NULL);
    if (!fun)
        return JS_TRUE;
    for (fp = cx->fp; fp; fp = fp->down) {
        /* Find most recent non-native function frame. */
        if (fp->fun && !fp->fun->native) {
            if (fp->fun == fun) {
                JS_ASSERT((uintN)JSVAL_TO_INT(id) < fp->fun->nargs);
                *vp = fp->argv[JSVAL_TO_INT(id)];
            }
            return JS_TRUE;
        }
    }
    return JS_TRUE;
}

but now it's

JSBool js_GetArgument(JSContext *cx, JSObject *obj, jsval id, jsval *vp)
{
    return JS_TRUE;
}

and it changes the behaviour of function paremeters inside with statements
as follows. it will not find the actual passed value anymore.

function MyFunc( par )
{
    with( MyFunc ) {
        y = par;
    }
}

why is it so?
