[Jprogramming] Writing J

[Tracy Harms]

My experience has been that my openness to long chains of modifiers has
increased as I get better at reading J. Also, I find value in the
widespread idea that seven, plus or minus two, is a count of things that
people can keep in mind simultaneously. I don't think it's worth proposing
specific standards for what counts as "a thing" for such tallying, but do
think it's worth noticing as a rough guide.
