    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
