Hmmmm. To make bitsets more useful I would like to see Select take a bitset
as its index argument. So that if you had a script like this:
bitset: make bitset! 8
insert bitset 3
insert bitset 5
select/many [a b c d e...] bitset
it could return [c e] as a result. Similar idea for Pick At etc.
Could be good for complex "database queries".
If this is what you originally meant, then I apologise for misunderstanding
you.

No problem. Sometimes an enhanced reply is just what is needed, sometimes
not. Sometimes it is just what someone else on the list needs :^)
