I was asking how you would conform a value to a falsey value. If the interface for the function is that returning nil or false means that the input is not valid (which is what I understood from the discussion) then how can you conform to nil or false? However, on reading the docs for conformer that you posted here, it suggests that returning falsey values does not mean that they are invalid, only :clojure.spec/invalid means that. So apologies for the misunderstanding. I was away from a computer that I could reasonably run a REPL on, so I just asked rather than tested ;)
