UnrelatedString

This is not in fact the case--`D` outputs a singleton list as desired, but Jelly [unwraps singleton lists](https://github.com/DennisMitchell/jellylanguage/blob/70c9fd93ab009c05dc396f8cc091f72b212fb188/jelly/interpreter.py#L1085) when printing them. For accurate/unambiguous representations of values, I recommend getting in...

Haven't watched the video (and sorry for the late reply), but the issue here is that Jelly doesn't parse arguments to the program the same way as it parses literals...

Oh, incidentally, if you ever want to drop by [Jelly Hypertraining](https://chat.stackexchange.com/rooms/57815/jelly-hypertraining), just let a mod know and they can unfreeze it.
