I think we already emit the error you'd like (and probably have done so for
quite some time):

$ cat k.f90
  function f2 (fn, i)
    integer :: i, fn
    character (len = fn (i)) :: f2
  end function f2
$ gfortran -c k.f90
k.f90:3.20:

    character (len = fn (i)) :: f2
                   1
Error: Function 'fn' at (1) must be PURE


Is there anything more than that?
