  Performs the following context-free rewritings:

  Performs the following context-free rewritings:

  - Places all pattern variables in Bind nodes. In a pattern, for identifiers x:

                  x  => x @ _
                x:T  => x @ (_ : T)
  

  • Removes pattern definitions (PatDef's) as follows: If pattern is a simple (typed) identifier:

           val x = e     ==>  val x = e
           val x: T = e  ==>  val x: T = e
    

  if there are no variables in pattern

         val p = e  ==>  e match (case p => ())
  

  if there is exactly one variable in pattern

         val x_1 = e match (case p => (x_1))
  

  if there is more than one variable in pattern

         val p = e  ==>  private synthetic val t$ = e match (case p => (x_1, ..., x_N))
                         val x_1 = t$._1
                         ...
                         val x_N = t$._N
  

  - Removes function types as follows:

         (argtpes) => restpe   ==>   scala.Function_n[argtpes, restpe]
  

  - Wraps naked case definitions in a match as follows:

         { cases }   ==>   (x => x.match {cases}), except when already argument to match
