 The syntactical precedence of match expressions has been changed.
 `match` is still a keyword, but it is used like an alphabetical operator. This has several consequences:
 
- 1. `match` expressions can be chained:

+
+   ```scala
+   xs match {
+      case Nil => "empty"
+      case x :: xs1 => "nonempty"
+   } match {
+      case "empty" => 0
+      case "nonempty" => 1
+   }
+   ```
+
+   (or, dropping the optional braces)

+      case x :: xs1 => "nonempty"
+   match
+      case "empty" => 0
+      case "nonempty" => 1

+
+2. `match` may follow a period:
 
     ```scala
-    xs match {
-       case Nil => "empty"
-       case x :: xs1 => "nonempty"
-    } match {

+       case _ => true

- 3. The scrutinee of a match expression must be an `InfixExpr`. Previously the scrutinee could be followed by a type ascription `: T`, but this is no longer supported. So `x : T match { ... }` now has to be
- written `(x: T) match { ... }`.

 ## Syntax
 
 The new syntax of match expressions is as follows.

 ```
 InfixExpr    ::=  ...
                |  InfixExpr MatchClause
