For those not familiar,
Y in Jelly joins a list of strings (actually a list of lists of characters) with a newline. In plenty of challenges with text output, Jelly submissions will put
Y in the footer on TIO, which I have taken advantage of as well. (TIO with
Y the output would be the same text on a single line with no delimiter (TIO without
In the same challenge I linked to there is an 05AB1E submission that returns a list of lines but the lines are clearly delimited in the output as elements of a list. In Jelly, however, any grouping of characters in lists gets ignored in the output.
My question is this: why do Jelly submissions get to forgo counting
Y in the byte count if it is necessary to delimit portions of the output?
Not that I want my Jelly answers to have to have one extra byte from time to time, I just don't see the logic behind allowing this.
