Detailed Description

Track the scope we are currently in to build a properly scoped variable.

The AST only knows about absolute scopes (namespace, struct, class), as once a declaration is parsed it is either in a scope or not. Each request to give me the namespace automatically leads to the entire scope the item is in. This makes it hard to have constructs like this:

 struct One
 {
    static const int o{};
 
    struct Two
    {
        static const int d = o;
    };
 
    static const int a = Two::d;
};

Here the initializer of a is in the scope One::Two::d. At this point the qualification Two::d is enought.

ScopeHelper tracks whether we are currently in a class or namespace and simply remove the path we already in from the scope.
