By > exposing all knobs, then such discussion might not ever happen? My remarks were not aimed at exposing knobs but to provide some debugging aid. Say e.g. there is a bug in the avx implementation that isn't present in the C version, or vice versa. Or in rhashtable but not hashtable. Right now it requires some guesswork to figure out what set backend is actually used for @myset, and it might make things easier for debugging if one could query the kernel for some information wrt. what set backend is used. I would try to avoid to expose anything that can't be ripped out again, so e.g. names or even just %pF of ->lookup() would perhaps be enough.
