Ruby as of 3.0 stopped shipping Set. Sorted_set was split out of Set since it needed the external library rbtree for decent performance.
Here are the three gems to import and make them available for Ruby 3.0/3.1 I've marked the FLAVORS as just "ruby30 ruby31" since ruby27 has them built in and jRuby has its own implementations built in still. ok to import? --Kurt
