Well, of course I think this is an absolutely dreadful idea.
(It would make more sense to limit co-arrays to only being available
in COMMON blocks.)  There are so many problems with it that I
wouldn't know where to start.  This isn't improving anything, it
is going to extraordinary lengths to try to ruin it.

Furthermore, it is out of order.  I am not joking.

WG5 agreed the requirements.

J3 passed the specs.

J3 passed the syntax.

J3 passed the edits.

We are now half-way through document review.
