polymorphism - An unexpected universe level -


here definition similar 1 in data.list.all:

open import data.vec  data {α π} {a : set α} (p : -> set π) : ∀ {n} -> vec n -> set π   []ₐ  : p []   _∷ₐ_ : ∀ {n x} {xs : vec n} -> p x -> p xs -> p (x ∷ xs) 

why all lie in set π?

agda version 2.4.3.

agda 2.4.2.4 , agda 2.4.2.5 (the maintenance branch) report expected error when all lives in set π, accepted agda 2.4.3 (the master branch).

please reports issue in agda bug tracker.
