My impression is that earlier [] == [] used to give a type error. Now it gives True.
So 1. Which instance of == is being used? 2. Is there some option controlling this behavior?
The instance being used is (), and it's controlled by -XExtendedDefaultRules. https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/interactive-... -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
