It's a nice tool, and I wrote this package just to learn J faster. I wrote some time ago a package that takes a range, maps elisp code over it and inserts it, e.g m4(* x x) becomes 0 1 4 9 16. Then I realized that the parens and spaces weren't really necessary and now this works as well: m4*xx. After learning some of J, I see that even arguments aren't necessary, e.g. m4*: describes the same thing in J. If you want to try the package, it's called "tiny" in MELPA. It's got one interesting application for org-mode: schedule/deadline an activity for a span of days: m0\n4|** TODO Something work-related %(1+ x)\nSCHEDULED: <%(date "mon" x) 10:00 +1w> expands to: ** TODO Something work-related 1 SCHEDULED: <2013-12-23 Mon 10:00 +1w> ** TODO Something work-related 2 SCHEDULED: <2013-12-24 Tue 10:00 +1w> ** TODO Something work-related 3 SCHEDULED: <2013-12-25 Wed 10:00 +1w> ** TODO Something work-related 4 SCHEDULED: <2013-12-26 Thu 10:00 +1w> ** TODO Something work-related 5 SCHEDULED: <2013-12-27 Fri 10:00 +1w> > If you have time to put some documentation up on Worg as a new  > linked from  that'd be great.
