Agreed on all counts. I've been starting to think oidtree/cbtree would be better done as BSD-style macro-defined functions (similar to how khash.h is, or sys/{queue,tree}.h on *BSD systems). I prefer Linux(kernel)-style container_of generics since I find them easier-to-follow and have extra type-checking, but with a flex-array it's not pedantically correct. So I guess using CPP like khash does might be a better way to go, here. Thoughts? Side note: I've also been considering Perl as a more powerful CPP replacement so I could use the same code for a persistent on-disk store (it would be easier to swap in pread/mmap use). An on-disk format could make it good for refs and pre-packed object storage (perhaps replacing loose objects).
