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.
