Yes, after thinking through the internal and external APIs, and the
FOLL_* situation, that sounds like the best overall approach right now,
IMHO.
I also considered whether adding some naming hints on top (suffixes such
as _INTERNAL) might help, but so far, it looks like it would add more
clutter than is justified. Instead, just looking at where the FOLL_*
flag is defined seems like it could be enough. And there aren't *too*
many flags, after all.
thanks,
