[Bug c++/25006] failure "using" a name contained in a class



------- Comment #3 from reichelt at gcc dot gnu dot org  2005-11-30 21:09 -------
This is really invalid code.

Paragraph [7.3.3]/6 states:
  A using-declaration for a class member shall be a member-declaration.

In your code snippet "using ::Foo::Bar::FooBar;" is a using-declaration
for "FooBar" which is a class member of the class "::Foo::Bar". But since
the using-declaration is not inside a class, it is not a member-declaration
- which violates [7.3.3]/6.

Or the other way round: Because the using-declaration for "FooBar" is not
inside a class, it cannot be a member-declaration according to [7.3.3]/6.
Therefore "::Foo::Bar" cannot be a class-name - it has to be a
namespace-name. And that's what GCC's error message says.
