    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

PatternContextSensitive

trait PatternContextSensitive extends AnyRef

Methods which implicitly propagate the context in which they were called: either in a pattern context or not. Formerly, this was threaded through numerous methods as boolean isPattern.
