  Solving this instance requires the newtype constructor N to be in scope.

while checking that type forall (a :: Type) (b :: Type). Coercible @Type a b => a -> b
  is at least as general as type N a0 -> a0
while checking that expression coerce
  has type N a0 -> a0
in value declaration unwrap

where a0 is a rigid type variable
        bound at (line 8, column 10 - line 8, column 16)
