<pre>Given the source below, Clang produces a warning by default about the use of
`A::` as part of the //declarator-id// of a declaration within the namespace
`A`. The warning about "extra qualification" is unwarranted because removing
the qualification causes the redeclaration of an inline namespace member to
stop being a redeclaration of the said member.
### SOURCE (<stdin>):
namespace A {
inline
namespace Q {
void f();
}
void A::f() { }
}
### COMPILER INVOCATION:
clang -cc1 -fsyntax-only -xc++ -
### ACTUAL OUTPUT:
<stdin>:6:11: warning: extra qualification on member 'f'
[-Wextra-qualification]
void A::f() { }
^
1 warning generated.
### EXPECTED OUTPUT:
(no warning)
### COMPILER VERSION INFO (clang++ -v):
clang version 11.0.0 (<a href="https://github.com/llvm/llvm-project.git">https://github.com/llvm/llvm-project.git</a>
