scala-either-extras

[now somewhat enhanced] 20-odd line Scala type-class substitute for Scalaz for validation

scala-either-proj-map-returns-proj

scala.Either modified so that lp/rp.map returns a Left/RightProj (instead of Either), thereby enabling definitions in for-comprehensions [see add_right-bias_2-10_withFilter branch for latest thinking]

scala-checking

yet another equivalent of a biased scala.Either: Okay/Reason extends Checked, complete with <*>.
