append_list : forall {a : Type} 
            . List a -> List a -> List a
Append two lists

         . {((1 : s)) ≤ r, Pushable r} =>
    (List a) [r] -> List (a [r])
Push a graded modality inside a list (defined as push @List)
pullList : forall {s : Coeffect, r : s, a : Type} 
         . List (a [r]) -> (List a) [r]
