@Adnan Is this a bug, or supposed to not work: Using k with a sublists as a and a list of lists as b. In the Legacy it just returns -1 and in the Elixir it checks each individual item. I would have assumed an output like 3 here.

@KevinCruijssen If what you want to do is check if the list is in the list of lists, you should have the lists reversed. It would result in [-1,-1] though and .k results in -1.

Since the implicit input will make the arguments reversed

Challenge: tio.run/##yy9OTMpM/f//3LZzW6Nq7RJc1HUPT1fX1ju8I/… make a bounding box, given a list of coordinates. I've tried symmetrical, mirroring, insertion, etc... can't get it in less.

@Emigna Ah, you're right, I mixed them up.. I would still expect an output of 3 instead of -1 though.

Also, regarding the code provided by @MagicOctopusUrn above. Shouldn't €Z work exactly the same as εZ}? I know Z doesn't pop the list, but shouldn't € also just take the top of the list as mapped value like the ε..

@Adnan I think .Λ is bugged right now. It works exactly the same as Λ, even though the docs say it is saved as a string. But I can't do anything with this string. Can't replace or insert characters, nor use .B to convert it to a newline delimited string-list.
