struct A{
struct Name{};
void Name(){}
};
struct B:A{
using A::Name; //#1
};
int main() {
struct B::Name d;
}
According to [basic.lookup#general-4], the lookup set occurs at `#1` would
discard the declaration of class "Name" since there is another declaration be
found. [namespace.udecl#1] just requires these type declarations are ignored
when checking for ambiguity but are not actually ignored in the the set of
declarations.
