Firefox agrees with this. I would close as invalid, but there is one case we do fuck up: <script> a = 1; </script> <script> var a; delete a; alert(a); </script> the existing a should prevent the creation of a new static slot for a, so the delete should succeed in this case. 84964 2 oliver 2008-07-02 02:37:34 -0700 Happily we've already fixed this bug. Closing as invalid because the original bug was not valid, and my updated bug was actaully already fixed. 84970 3 zwarich 2008-07-02 03:09:17 -0700 I added a test for the second scenario that Oliver mentioned in r34952, because we did not have any existing coverage of this case.
