I'm never sure what to call it, so I just reroll it into _ as needed. It's pretty easy for me to remember, but I'll probably tattoo it on my chest just in case. So... for any given class, it returns a tweaked version that unpacks an iterable of its arguments instead of taking separate args. Interesting, perhaps, but not something that'll be needed in the stdlib. But as a demo of how easily Python primitives can be combined into some fairly elegant code, I think this is as good as any!
