Recursion schemes implemented in Scala using Matroyshka. They don't all make sense or anything, but they compile and run. lo

	package prestwood

	// Examples of recursion scheme implementations using matroysha. Mostly they're not that useful,
	// and I really only got three tricks down, but they're good tricks:

	// 1. Collect information across an AST using a Writer monad
	// 2. Modify AST nodes in place
	// 3. Annotate AST nodes with arbitrary types

free monads using scalaz. Example of composing interpreters.

	package testfree
	import testfree.Console._
	import testfree.Authorization.{ Authorize}
	import scalaz.{Inject, _}
	import Scalaz._
	import scala.io.StdIn
	import scalaz.Inject._

	// Example of using two separate ADTs with separate interpreters and composing the interpeters.
