Detailed Description

Checks if an unused forward declaration is in a wrong namespace.

The check inspects all unused forward declarations and checks if there is any declaration/definition with the same name, which could indicate that the forward declaration is potentially in a wrong namespace.

namespace na { struct A; }
namespace nb { struct A {} };
nb::A a;
// warning : no definition found for 'A', but a definition with the same
name 'A' found in another namespace 'nb::'

This check can only generate warnings, but it can't suggest fixes at this point.
