Pipeline operator in scala
There isn't much that can be reviewed. If you use Scala 2.10 then you should use an implicit class instead of an implicit conversion. Even better: use an implicit value class:

implicit class PipelineContainer[F](val value: F) extends AnyVal {
  def |&gt;[G] (f: F =&gt; G) = f(value)
}


Furthermore, in Scala, type parameter are enumerated starting with an A, but this is more a style issue.
