I have the following C++ code and want to give the D/C++ integration a new try:

        template<typename T> class Array {...}
        class myClass {...}
        typedef Array<myClass> myClassArray;
        myClassArray classA::getArray() noexcept {...}

How does the D binding for this look like? I tried something like this:

 extern (C++) {
   class Array(T){};
   class Array(myClass) {};
   class classA {
     final Array(myClass) getArray(); <== COMPILER ERRORS
   };
 }
But this doesn't work at all and give a bunch of comiler errors:

Error: function declaration without return type. (Note that constructors are always named this)

Error: no identifier for declarator extern (C++) Array(myClass)
Error: semicolon expected following function declaration

Error: function declaration without return type. (Note that constructors are always named this)

Error: no identifier for declarator extern (C++) getArray()


Any ideas?

final Array!myClass getArray(); <== !!!!!!!!!!!!!!!!!
