Apologies in advance if I'm missing the mark (haven't been
able to really read this or any other thread very deeply
lately, but isn't the situation you are addressing one of sets:
-------------------------------------------------------
;- given data of the form:
data: {^^(ted|admin|bobr|andrew|elan|keith|cheryl|joel|brady)$}
split-it: func [what][difference parse/all what "^^|$()" [""]]
split-data: split-it data
users: ["ted" "admin" "bobr" "andrew" "elan" "keith"
"cheryl" "joel" "brady"]
some-other-data: split-it {^^(tom|dick|harry|ted|ivan)}
whos-in: intersect some-other-data users == ["ted"]
whos-out: differece whos-in some-other-data == ["tom" "dick" "harry" "ivan"]
-------------------------------------------------------
If not, pardon my intrusion in this knowledge base building
thread.
(Wondering to myself: if polymorphic set operations were
available in languages that rely heavily on regular
expressions, would those regexps still be used just as much?)
