I made a block, (do ({} @addInput) to $list-1 :: lists)
which just gets the list, does an operation on it, and returns the result. While using it, I did a silly little goof which is leaving one of the inputs empty. You know what happened? I made a recursive list.
It's pretty useless since the ([ V] of $list-1)
block just throws an error when trying to use it on the list. Just a cool little thing I found, thought I wanted to share with you guys.
