Yes, the slogan defining Simple J is only a slogan. I would cheerfully
sneak in
4!:0 <'each'
1
each
&.>
as an adverb and
mm =: +/ . *
4!:0 <'mm'
3
as a verb.
If someone can do what you do below, he no longer needs Simple J, simply
understood, and can probably do it instead as an easily understood
explicit verb.
