I've been working for some years on some libraries for doing #OOP with C. One rule I applied to my own efforts was: no code generation or pre-processing you can't do with the standard C pre-processor. (Another rule: no crazy pre-processor tricks, just standard macros.)
Dmitry Frank's method is generally fairly clean, but it does require boilerplate code generation. Some good ideas there though.
Rusted Neuron is an invitation-only 'Intentional Community'. It is not intended to represent a specific focus, although the people you find here are generally intelligent, creative, and witty. Content and conduct rules are set by the community, not by fiat. The one thing we will not tolerate here is intolerance; you can agree to disagree, but you must treat others with respect.Currently the membership limit is 100 people and there are plenty of slots available. The goal is to try to replicate real-world community interaction and norms enforcement online. Keeping it small is intended to create a village atmosphere by staying well under Dunbar's Number.
