[MPIWG Fortran] Assumed-size array in MPI3

  I read a Fortran textbook, which says "Assumed-size dummy arrays are a
holdover from earlier versions of Fortran. They should never be used in any
new programs".
  But I find MPI3 has interfaces like

MPI_Alltoallv(sendbuf, sendcounts, sdispls, sendtype, recvbuf, recvcounts,
rdispls, recvtype, comm, ierror)
 INTEGER, INTENT(IN) :: sendcounts(*), sdispls(*), recvcounts(*), rdispls(*)

  I was wondering why MPI3 still uses it.
