    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

sealed 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.

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
