C++ namespace alias in entire class scope

Question

I expected to be able to use a namespace alias in a class declaration but get a compiler syntax error.

struct MyClass
{
    namespace abc = a_big_namespace;
             


        

Answer 1

The scope of a namespace alias is a code block.

So you can put it in any code block.

BUT, you can't put it inside a class, because that will mean it's a member of the class.
A namespace alias can't be a member.
