Dear Members of Fortran WG: Hubert pointed out that we have to provide MPI_Op_create_l and MPI_Register_datarep_l functions in the F08 bindings since generic function overload is not possible for these two functions (the only difference in the two versions of these functions is the argument of type procedure and these two procedure arguments are not distinguishable, more details from Hubert at: https://github.com/mpi-forum/mpi-issues/issues/137#issuecomment-648725841). The question for the Fortran WG is: Is there a better solution than adding the _l functions for these two cases? If not, are you all OK with making an exception for these two cases and adding _l functions? Thanks, Puri
