At the risk of splitting hairs..., I thought an iterator doing '++'
followed by an iterator doing '--' to be a complicated way of counting,
(compared to a single '++' pass). And, repo_stat_inc(.., STYPE_FUNC)
('repo stat increment') actually doing a decrement seemed unintuitive :)

Thanks, will do.

perhaps repo_stat_count_nca() ?

I included the two feedbacks from your follow-up email in my tree
(remove comment and garbage collect STYPE_NONFUNC + STYPE_FUNC).

Kind regards,
