Hello Blake,
After having asked you to present a use case where the behavior of
box/unbox differs from enclose/disclose and you graciously replied, I
felt obligated to spend a little time studying the issue. I did that
and have come to the conclusion that both boxed and nested arrays are
overkill for the use case. The key-value pair text (separated by a
blank) or key text can be supplied in a character vector which can
easily be parsed for the presence of one or two words. See the attached
blake1.apl.gz for a demonstration.
I would like to make the observation that nested arrays must not be too
bad. After all, the revised code to fix their shortcomings only took 5
lines written in terms of nested arrays.
Regards,
Fred
