I imagine that this topic is of low priority to practically every J
programmer who has a mastery of the language and because they are so used
to the present notation of rank in, say, NuVoc.
For example, why is the brief definition of >. displayed as
Larger of
0 Ceiling • (Max) 0 0
... instead of Larger of
Ceiling 0 • 0 (Max) 0
... and in every other such reference?
The rank applying to the left and right arguments should simply be put on
the left and right of the words they refer to.
For nomadic words rank should be displayed on the right, while for dyadic
words the ranks pertaining to left and right arguments should be on the
left and right of the English or punctuation name of a word.
The present notation can easily be misinterpreted, as in:
Take Rotate _ _ , which applies rank to arguments x and y. Should this not
be _ Rotate _ to both identify Rotate as being dyadic and show the ranks of
of its arguments.
This trivial change would simplify J documentation by making it more
accurately represent how rank is applied.
