 100 // define. It should compare the two type-info structures
 101 // it is given and return true if they represent the same type
 102 // and false otherwise. You also have to supply a function
 103 // to generate your type-info structure. You do this through
 104 // the LUABIND_TYPEID() define. It takes a type as it's
 105 // parameter. That is, a compile time parameter. To use it
 106 // you probably have to make a traits class with specializations
 107 // for all classes that you have type-info for.
