IDL43 — Need the concept of a "using namespace" directive to simplify IDL files

Programming languages that have the concept of modules/namespaces also include the concept of "using" a namespace type such that one can ommit the explicit reference to the 'used' namespace.

The following is an example for C++:

Assume the declaration:

namespace MyNamespace
{
    class MyClass
    {
    public:
        void my_operation() {}
    };
    void MyFunction1(MyClass) {}
}

Normally these types need to be accessed using their fully qualified names:

MyNamespace::MyClass obj;
obj.my_operation();
MyNamespace::MyFunction1(obj);

This can be cumbersome when having to reference a lot of types in the same namespace, specially for deep nested namespaces.

The C++ using declaration can bring the name space or individual types into scope simplifying the coding as in:

using MyNamespace::MyClass;
MyClass obj;
obj.my_operation();
MyFunction1(obj);

Or alternatively bringing every type in the name space into the scope:

using namespace MyNamespace;
MyClass obj;
obj.my_operation();
MyFunction1(obj);

Java and C# provide similar facilities:
In Java the "import" keyword is used to import packages or types into the scope. The syntax is:

import package.name.ClassName;   // To import a certain class only
import package.name.*;

In C# the "using" keyword is used to import namespaces or types into the scope. The syntax is:

using  MyNamespaceName.MyClassName;   // To import a certain class only
using MyNamespaceName;

This issue request that a similar facility is added to IDL
