I agree with Dave's position.  I think WG5 needs time to collect feedback 
from the field as to coarray applications before rushing into new feature 
development.  Also WG5 needs to wait for most compiler vendors to support 
and gather experience with coarrays before committing itself to more 
features.  Coarrays, as it is in F08, is not a mature language feature and 
needs more additions.  But WG5 needs time to get the additions right. 
Simply starting with N1858 is a wrong choice to me.
