Remark: The kernel was already using Sort. So, the limitation was artificial. Moreover, it may seem unnecessary to have quotients of proofs in a proof irrelevant system, but this is useful for proving a more general funext lemma. This more general version is needed in the new tested contributed by @digama0. |
