   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))
       }

9. #### 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 SI-1503, SI-5024: don't cast binders to types we're not sure they have

   TODO: update spec as follows (deviation between `**`):

   A pattern binder x@p consists of a pattern variable x and a pattern p. The type of the variable x is the static type T **IMPLIED BY** the pattern p. This pattern matches any value v matched by the pattern p **Deleted: , provided the run-time type of v is also an instance of T, ** and it binds the variable name to that value.

   Addition: A pattern `p` _implies_ a type `T` if the pattern matches only values of the type `T`.
