Proposed resolution (February, 2012):

Change the grammar in _N4567_.5.1.1 [expr.prim.general] paragraph 8 as follows:

    qualified-id:
      nested-name-specifier templateopt unqualified-id
      :: identifier
      :: operator-function-id
      :: literal-operator-id
      :: template-id
    nested-name-specifier:
      ::
      ::opt type-name ::
      ::opt namespace-name ::
      decltype-specifier ::
      nested-name-specifier identifier ::
      nested-name-specifier templateopt simple-template-id ::

The resolution of issue 355 failed to update the grammar for class-head-name in Clause 11 [class] paragraph 1 and removed the optional :: from class-or-decltype in 11.7 [class.derived] paragraph 1, with the result that it is still not possible to globally-qualify a class name in a class definition, and the ability to globally-qualify a base class name has been lost.
