[Patch, Fortran, 4.7] PR 18918 - Add initial support for a coarray communication library

[Rouson, Damian]

If I understand this correctly (and if you all don't mind a user
contributing to the discussion), this would be a big plus.  What I like
the most about Fortran 2008 coarrays (besides the elegant syntax) is the
implementation-independence.  What the standard refers to as an image
could presumably map to an OpenMP thread on one platform, a MPI process on
another, or some mix thereof.

On related note, what will be even better will be if a future standard
allows the programmer to determine the mix in order to map processes to
nodes on a distributed platform and threads to cores within the node.
