@MartinEnder I've found an ordinal mode way to split a string on the stack in half: ..Y;m;!?z?

ah, very nice :)

Basically, Y gives us a string with half the length, m truncates the old one to this length (so we get the first half), and z drops the first half from the full string, getting us the second one

Making it work correctly with odd length strings might be too hard

and making it work with ' in the middle of the code ;)

well, I don't know how to deal with that in any case :D

I think the only general solution is to pull the next character into the first half and then pad the second half with an additional space

Toeplitz challenge solution. I'm particularly proud of how I managed to use j in ordinal mode :)

I'll post it as soon as I have some time to explain it adequately (and maybe golf it better)

that looks pretty good

I haven't tried golfing mine yet

I wanna try another approach though where I don't read them one line at a time

I understand just now your solution, I like how you used Z!

meanwhile: codegolf.stackexchange.com/a/121599/8478

looking forward to your 9-byte Cardinal solution :P

hm, I wish I had a good alternative for &w...k that can also do 0 repetitions

@MartinEnder better to avoid it, codepoint input would be expecially awkward in this challenge :P

nice idea with the tape, by the way!

At least one byte can be golfed by letting the IP bounce

@Leo oh cool, I tried something similar but couldn't get it work out. I like how the ] is actually necessary to make the ! not mess stuff up
