Is there a private using name = type;

Question

I want to write:

namespace A{
    using name = type;
}

But if I try to use it from another space it would be available. Can I make it private inside its namespace?

Answer 1

There's no language feature to allow that, but many projects have the convention that all contents of namespaces named detail are reserved and should not be used.

namespace A {
    namespace detail {
        using name = type;
    }

    //something using detail::name
}

//A::detail::name technically accessible, but disallowed by convention
