>From bitbucket.org/atlassian/fugue

"This library attempts round out some of the deficiencies that a functional
programmer finds when using Guava. In particular it provides Option and
Either types similar to the Scala library as well as a Pair."

The lambda-dev post that Brian referenced in earlier in this thread was
written by Jed Wesley-Smith, who has committed most of Fugue's code.
