  1. trait MatchMonadInterface extends AnyRef

    Interface with user-defined match monad? if there's a __match in scope, we use this as the match strategy, assuming it conforms to MatchStrategy as defined below:

    Interface with user-defined match monad? if there's a __match in scope, we use this as the match strategy, assuming it conforms to MatchStrategy as defined below:

    type Matcher[P[_], M[+_], A] = {
      def flatMap[B](f: P[A] => M[B]): M[B]
      def orElse[B >: A](alternative: => M[B]): M[B]
    }
    
    abstract class MatchStrategy[P[_], M[+_]] {
      // runs the matcher on the given input
      def runOrElse[T, U](in: P[T])(matcher: P[T] => M[U]): P[U]
    
      def zero: M[Nothing]
      def one[T](x: P[T]): M[T]
      def guard[T](cond: P[Boolean], then: => P[T]): M[T]
    }

    P and M are derived from one's signature (def one[T](x: P[T]): M[T])

    if no __match is found, we assume the following implementation (and generate optimized code accordingly)

    object __match extends MatchStrategy[({type Id[x] = x})#Id, Option] {
      def zero = None
      def one[T](x: T) = Some(x)
      // NOTE: guard's return type must be of the shape M[T], where M is the monad in which the pattern match should be interpreted
      def guard[T](cond: Boolean, then: => T): Option[T] = if(cond) Some(then) else None
      def runOrElse[T, U](x: T)(f: T => Option[U]): U = f(x) getOrElse (throw new MatchError(x))
    }

  11. def binderTypeImpliedByPattern(pat: Global.Tree, pt: Global.Type, binder: Global.Symbol): Global.Type

    Compute the type T implied for a value v matched by a pattern pat (with expected type pt).

    Compute the type T implied for a value v matched by a pattern pat (with expected type pt).

    Usually, this is the pattern's type because pattern matching implies instance-of checks.

    However, Stable Identifier and Literal patterns are matched using ==, which does not imply a type for the binder that binds the matched value.

    See scala/bug#1503, scala/bug#5024: don't cast binders to types we're not sure they have
