Dunno, but it is something I have been badgering about for some time.
I hope so.

That statement is a great help.  My problem previously was that I
couldn't point to a reference saying that MPI badly needed it, so it
was ruled out of scope.

And therein hangs a tale :-(

There are some evil issues there, to do with scoping etc.  I am trying
to get the TR enhanced enough to be a starting point, but it doesn't
help that the current interoperability section and C standard are very
bad on the point.  The main body of Fortran is merely weird and fiendishly
complicated (because of much history) ....
