We have to be a bit careful about statement like
do concurrent(i=1:n, a(i)>sum(a)/n)
a(i) = a(i) * 0.5
end do
which really have to be before the execution
of the loop body itself.

Quote from the standard:

The key paragraph is [176:22]:
"At the completion of the execution of the DO statement, the execution cycle
begins."

Note that one needs to be careful to handle OpenACC/OpenMP correctly to make
sure that, e.g., "!$acc loop" remains attached to the loop it belongs to.
