Summary: Lua: C++ typename check fails for equally named classes

Initial Comment:
 
 Suggest you have two SWIG modules, "A" and "B". Also suggest you use 
 different namespaces in both modules with equally named classes, say:
 
 library A:
 
 namespace A
 {
 class classname
 {
 //! constructor
 classname(const std::string & ident);
 ...
 };
 }
 
 and library B:
 
 namespace B
 {
 class classname
 {
 //! constructor
 classname(const int & id);
 ...
 };
 }
 
 Then both libraries will be wrapped by SWIG into 2 different modules 
 and linked together. In Lua, you expect to be able to call:
 
 a = A.classname("hello") -- call constructor of A::classname
 b = B.classname( 3 ) -- call constructor of B::classname
 
 SWIG actually merges equally class names from different namespaces into 
 one. That is, if the load_module routine of module A was called before 
 B, then it expects the syntax of A::classname, if B.classname( ... ) is 
 called.
 
 I am using latest SWIG 1.3.40
 
 
 Best regards
 Sebastian
