How 'bout an actual set.el library?

Do you mean a set library with a new data structure that'd be
`seq'-able, similar to stream.el?

Cheers,

No, rather a set.el library much like the seq.el and the
map.el libraries, which would offer set-union, set-intersection,
set-equal, on top of various concrete representations (lists,
hash-tables, bool-vectors, you name it).
