  • Sets now override equal? and the hash-code operations. For example, (equal? (list->set '(1 2 3)) (list->set (3 2 1))) is now #t.
  • The behavior may not be quite right yet for circular data structures involving sets.

  • Changed naming convention: most operations have a set- or seteq- prefix now, which is more consistent with Scheme conventions and obviates the need for requiring the modules with a prefix.
  • Added a default main.ss module, which exports everything.
  • Added set-count operation. Thanks to Jay McCarthy for the suggestion.
  • Added in-set operation; also sets are now sequences.
  • Created Scribble docs.
  • Documented a few more previously-undocumented operations.
