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))
   }
