FoldTest.scala

package foo

import org.junit.Test

import scalaz._
import Scalaz._

import org.junit.Assert._
import org.hamcrest.CoreMatchers.is

class FoldTest {

  @Test
  def testStd() : Unit = {

    // import scalaz.syntax.foldable._
    // import scalaz.std.AllInstances._

    val list = List(1,2,3)

    val res: Int = list.fold()
  }
}

does not compile, looks for fold in std TraversableOnce
