Ah, got to love Erik's old answers :P

I'll write up a brief explanation - the use of G in that answer is actually really clever

hyper-neutrino

ṣ”|⁶ṁ;ɗ\pG  Main Link
ṣ”|         split on "|"
   ---ɗ\    cumulatively reduce (over last three as a dyad)
   ⁶ṁ       mold space like the current list (basically replaces the last item with spaces as well)
     ;      and append the current item
        p   cartesian product with the comment item
         G  format into grid

essentially, it first splits on "|" into its components

for example, let's say we have a|bc|def

it becomes ["a", "bc", "def"]

and then we cumulatively reduce that

so we start with the empty list on the left and "a" on the right

⁶ṁ; molds " " to the empty list (being empty of course) and then appends the "a"

so our first item is just "a"

on the next step, we have "a" on the left and "bc" on the right

⁶ṁ; molds " " to "a" so we get " " and then append "bc" to get " bc" as our second item

on the third step, we have " bc" on the left and "def" on the right so we mold " " and get " " and then append to get " def"

so now we have a list of the lines

then, we take the cartesian product with "@" (or whatever the comment character is)
