Agreed.
A possible improvement would be to add `autohash` helper to `hashes` module. So
we avoid automating object identity and making it easier for people to auto
generate hashes for cases when it make sense.
proc autohash*[T: tuple|object](o: T): Hash =
var h: Hash = 0
for f in o.fields: h = h !& f.hash
!$h
proc hash*(v: Something): Hash = v.autohash
Run
