There are no virtual functions in integer_t; I think Vicente meant virtual inheritance of integer_t_data.
Virtual inheritance adds a little bit of overhead to member access - usually offsetting by a value stored in a virtual function table (which wouldn't otherwise be needed here). CRTP avoids this nicely. [...]
Ah, I wasn't aware of the overhead. Virtual inheritance was the first thing I saw that took care of the problem, and I didn't consider CRTP at the time I originally wrote that. Thanks for suggesting it. -- Chad Nelson Oak Circle Software, Inc. * * *
