           Summary: Array.prototype.toString should be generic

           Version: 528+ (Nightly build)
          Platform: Unspecified

          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

The following fails in JSC

Array.prototype.toString.call(document.getElementsByTagName('*'))

with a TypeError.

The spec is pretty clear here that the above should work.

15.4.4.2    Array.prototype.toString ( )

NOTE    The toString function is intentionally generic; it does not require that its this value be an Array object. Therefore it can be transferred to other kinds of objects for use as a method. Whether the toString function can be applied successfully to a host object is implementation-dependent.
