Suppose we wish to inspect our PATH. Then we can make it more readable using awk:

BEGIN {FS = ":"; OFS = "\n"}
{$1=$1 ; print $0}

This will give something like:

/Users/vanessa/.opam/default/bin
/Users/vanessa/.cabal/bin
/Users/vanessa/.ghcup/bin
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
/Library/TeX/texbin
...

We can do the same in Jacinda, viz.

fn path(x) :=
  [x+'\n'+y] |> (splitc x ':');

path¨$0

I think the functional style (especially the absence of global variables) is far preferable.
