[patterns] Match against a enum constant

[Tagir Valeev]

Hello!

Currently switch can match against a enum constant, e.g.:

  static void switches(TimeUnit t) {
    switch(t) {
    case SECONDS:System.out.println("Matches");break;
    }
  }

However it seems that this is no case for __matches operator:

  static void matches(TimeUnit t) {
    if(t __matches SECONDS) {
      System.out.println("Matches");
    }
  }

This cannot be compiled (even if I specify qualified
TimeUnit.SECONDS). Is this intended difference between switch and
__matches?

With best regards,
