Ah wait there is the sub command, I have to check the Aur.

As soon as possible I will compare them to mine.

That wasn't my intent. I was actually trying to force myself to use list commands wherever I could.

I consider SUB to be a list command in this context, since I am giving it a list and expecting one in return. I'm not exploding the list and doing anything with the elements. So to me, 3, 7, and 8 are all still variant A.

I'm also not sure why you would classify #6 as anything but variant A; the main steps used are SORT, DOSUBS (x2), and ΣLIST. Is there something going on with it that doesn't fit the "A" classification?

If I were to approach these as variant C, I would likely use sysRPL instead.

It's your challenge, so you get to make the rules as you see fit. I'll happily agree to whatever classification you choose for them.
