scala.tools.nsc.ast.parser.Parsers

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
