I really like that this works in NewRPL! Unfortunately, it doesn't in standard UserRPL -- NOT isn't recursive into the sublists, so it results in a "Bad Argument Type" error on a standard 50g.

My apologies, in my head the lines between userRPL and newRPL are becoming blurry, I can't recall the slight differences sometimes. All operators map element-by-element on lists on newRPL, but not in userRPL.

PS: On the other hand, the official rules forgot to ban newRPL, so perhaps I should get some timings....
