Thanks Raiph for your explanations about the whatever. It still looks very magical to me.
I'm curious what you meant by "duplicate removal phase" and would enjoy reading an elaboration of that.
If you grep multiples of 5 and multiples of 5 separately (in parallel, assuming Rakudo would parallelize junctions), you would end up with multiples of 15 on both streams, so you would need to remove those duplicate before proceeding to the summation.
