Dear all,

looking at the current draft of the T18508, I wonder why CO_BROADCAST 
accepts polymorphic arguments while CO_REDUCE doesn't.

I do not see a big difference between the two ? and implementation wise, 
a polymorphic argument also causes only little extra implementation 
work. By contrast, allocatable components (which can also be 
polymorphic) cause me much more grief. And those seem to be permitted 
for both.
