Source docstring:

takes a predicate function with the semantics of conform i.e. it should return either a
(possibly converted) value or :cljs.spec.alpha/invalid, and returns a
spec that uses it as a predicate/conformer. Optionally takes a
second fn that does unform of result of first

(defmacro conformer
  ([f] `(spec-impl '(conformer ~(res &env f)) ~f nil true))
  ([f unf] `(spec-impl '(conformer ~(res &env f) ~(res &env unf)) ~f nil true ~unf)))
