Chapel's domain concept could be a basis for enhancements to Fortran in
the future. However, I'd like to see some practical experience first.
HPF jumped into this area and hung itself with a bad design. Domains
would layer on top of our current arrays and co-arrays. Nothing is lost
by moving ahead with the current co-array design and then integrating a
coherent domain feature in the future. There is certainly not time to
start this (very large) feature for f08.
