Dear chapel-developers,
I often find myself doing multiple reductions of the same type in forall
loops (eg. multiple accumulators). The way I currently do this is to
specify separate reduce intents (as in the commented line in the code
below....)
(+ reduce sum1, + reduce sum2)
While this works fine, it would be nice to write this as
(+ reduce sum1,sum2)
or something like that (with a different delimiter, for instance).
I'll note that OpenMP allows specifying such common reductions over a list
of variables.
Any thoughts?
Thanks in advance,

------------------------------------------------
var sum1, sum2 = 0;
config const N=100000;
forall ii in 1..N with (+ reduce sum1,sum2) {
//forall ii in 1..N with (+ reduce sum1, + reduce sum2) {
sum1 += ii;
sum2 += ii*ii;
}
writeln(sum1);
writeln(sum2);
