You're right, I did read very quickly on this but it's the standard OR
operator being used differently:

So there would seem be be a need here since this is not yet implemented
if I am right.

I did study parallel algorithms back in my school days but I can try
recalling hypercubes and all that so that it becomes possible eventually
to implement such functionality in C++.
