      pure real module function getItem(id) result(res)
         integer, intent(in) :: id
         pointer :: res
      end
   end interface
   real, target :: items(10)
end module

submodule(A) A1

   pure real module function getItem(id) result(res)
      integer, intent(in) :: id
      pointer :: res
      res => items(id)
