They really are two separate (but related) issues. We were talking about the function labels. But they just inherit the "_f08" name for name mangling from the "mpi_f08" module name. Thus the linkage to the module name.

We had originally proposed the module name to be "mpi3" but this ties the name to a particular mpi version which didn't seem the right thing to do. I'm open to a different module name though Rolf will probably kill me. Perhaps "use mpi_f_types" or "use mpi_f_handles". Though it is late in the game to be making a name change now.

>>> I would request that any names NOT include text that refers to a specific version of the Fortran standard. The industry already made that mistake once with the .f90 file type meaning "free-form source" - I don't want to see the mistake repeated. Maybe "fdesc" can be used, or something else that has the right connotation without implying some specific standard revision.
