Glad to hear it, looking forward to seeing what you come up with! The question becomes, once you have the heterogeneous operations, is there any reason to keep the others around (my experience is that they simply become a distraction / attractive nuisance, and we're better off without them, but there may be use cases I haven't thought of that justify their inclusion).
When David and I are done revising the proposal, we would like to send you a copy. If you would be interested in reviewing, can you please let us know how to get in touch with you? David and I can be reached at {svoboda,weklieber}

>once you have the heterogeneous operations, is there any reason to keep the others around
The two-argument form is shorter, but perhaps that isn't a strong enough reason to keep it. Also, requiring a redundant 3rd argument can provide an opportunity for mistakes to happen if it gets out of sync with the type of first two arguments.
As for the non-generic functions (e.g., ckd_int_add, ckd_ulong_add, etc.), we are considering removing them in favor of having only the generic function-like macros.
