For elements that have to bee ditched in a destructuring operation, like `target, _ = some·generator()`, it’s possible to use a word that explicit this discard. One short one term for that is "lee", as in "Basest part, ‘dregs’, ‘refuse’[1]."
I wasn’t aware that many people disliked so much underscore and other YOLO approaches to morphe agglutination. I always felt sad that we had to endure this ridiculous typographical masochism that plague the whole industry. But going against a widespread habit, as absurd and sore could it be, is generally its own road to some form flagellation.
