43/// C++ nested name specifiers are the prefixes to qualified

45/// specifier. Nested name specifiers are made up of a sequence of
46/// specifiers, each of which can be a namespace, type, identifier
47/// (for dependent names), decltype specifier, or the global specifier ('::').
48/// The last two specifiers can only appear at the start of a
49/// nested-namespace-specifier.
