There is a gem, the Big "Formal" Test Suite (bfts) that is supposed to
be the most complete. It's the successor to Rubicon. As I recall, there
are two "Ruby standards" -- MRI (Matz' Reference Implementation), which
is Ruby 1.8.x and which jRuby, MRI itself, IronRuby, and probably most
other implementations are attempting to track -- and KRI (Koichi's
Reference Implementation), which is Ruby 1.9.x -- Ruby 2.

Pat Eyler is the person who most closely tracks the various
implementations of Ruby, so he'd be the logical one to go into more detail.
