Message: [QUOTE="Piyo, post: 2600320"] BTW, John, here is an idea. I think you can use templates to help create those concepts of non-copyable, etc. and derive from those templates to insure the concept. I hope this helps! BTW boost ([URL="http://www.boost.org"]www.boost.org[/URL]) has some examples of this idea in practice. [URL]http://www.boost.org/libs/utility/utility.htm[/URL] This shows the non-copyable concept. As for non-default constructable, I am not sure but I thought that if you only specify ctors that cannot be effectively reduced to a default constructor, it means that your class is non-default constructable. eg. Note: tested gcc3.4.3 and this class is non-default constructable. class A { public: A( int var ); }; This version can be default-constructable: class A { public: A( int var=0 ); }; Hope that helps!
