The code you posted is right, I can't give you a better example.

I still don't understand what you don't understand. :-)

A class has a name. Its name is stored in a symbol table, that is 
private to the project/component/library it is declared in.

An exported class has a second name, a public name, that is stored in 
another symbol table, the global symbol table, that is shared by the 
project and all components and libraries.

Before namespaces, the public name was always the same as the private 
name. As that name is shared by everyone, collisions may occur.

So the namespace feature just allows to choose what the public name is, 
using a convention: everything before ':' is the namespace, and two 
different people or organization should use different namespaces, to 
avoid collisions.

Once your public class name is "GianLuigi:MyClass", you have to use "New 
GianLuigi:MyClass" to instanciate the class outside of the 
project/component/library it is declared in.

Is it clearer now?
