Luke Palmer asked:
Of course, there will be a pragma or something to instruct it to
operate serially, yes?
I doubt it. Unless there's a pragma to instruct threads to operate
serially.
In any case, I'm not sure what such a pragma would buy you. The
ordering of evaluation would still be inherently unordered.
BTW, in thinking about it further, I realize that Dan is going
to have to tackle this issue anyway. There's fundamentally no
difference in the exigencies of:
$junction = $x | $y | $z;
foo($junction); # Call foo($x), foo($y), and foo($z)
# in parallel and collect the results
# in a disjunction
and
$junction = &f | &g | &h;
$junction($x); # Call f($x), g($x), and h($x)
# in parallel and collect the results
# in a disjunction
