Is there any widely applicable rule so that I don't come up with this inferior definition of zoop? It also matches all arguments, provably terminates and has the same type as foldr.

zoop abb b [] = b zoop abb b (a:as) = zoop abb (abb a b) as

@johannes-riecken you wrote foldl, which is just as good!
