rribeiroHi all! I'm with a little doubt. I have a goal of the form P (map (\x -> x . y . z) xs) and a hypothesis of with type P (map (\ x -> (x . y) . z) xs). Is it possible to rewrite the hypothesis to mach the goal without using function extensionality as a postulate?28/01 21:25

rribeiroglguy: Ohhh I forgot to say that "." is a custom operator not function composition. 28/01 22:36
rribeiroI'm looking for any tip (if there's any) to avoid axiom of function extensionality to solve something like this28/01 22:37
