Nat => ℕ

page 4 Nat should be ℕ

Agda is not very happy about:

data ℕ : Set where
  zero : ℕ
  suc : ℕ → ℕ
{-# BUILTIN NATURAL Nat #-}

but calms down, when receives:

data ℕ : Set where
  zero :     ℕ
  suc : ℕ -> ℕ
{-# BUILTIN NATURAL ℕ #-}

Lovely paper and with code! I thank, whatever gods may be, that you do not teach less well :)
