Yes it was! And very mind-bending in a very good way.

Probably would be good to give the para an argument to specify the number of processes to run in, defaulting to the cpu count (*2?) or so? As it is it is going to create a lot of processes, and will probably cause a speed hit in almost every case as the do: body is generally very simple (like {a, b, c} in your example) and all the work happens in the iteration and filters?

Very nice article though, shows how macros work and how to use them. :slight_smile:
