1411. More on global scope :: in nested-name-specifier

[Moved to DR at the April, 2013 meeting.]

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.

Proposed resolution (February, 2012):

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

qualified-id:
nested-name-specifier template_opt 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 template_opt simple-template-id ::
