I started reading through the Lean 4 documentation. funabst.md contains the examplefun (u : β) (z : α), u. Is this really correct Lean 4 syntax? Based on the preceeding documentation I was expecting fun (u : β) (z : α) => u. If it is correct syntax perhaps you could introduce it more explicitly, because I can't see where it is introduced.
