--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
The point of declaration of the 'test' template is after its complete
declarator, so it is not visible in its own trailing return type. Clang's
result is correct.

However, this code violates [basic.scope.class]p2: "A name N used in a class S
shall refer to the same declaration in its context and when re-evaluated in the
completed scope of S. No diagnostic is required for a violation of this rule."

So GCC's behavior is permissible too.
