switch statement and multiple default cases

Heya,

 

The spec states "There must be at most one default label." [1] which is
surely the right way to go IMO but not even the PHP implementation (5.5.9)
behaves like this and the following is perfectly valid:

 

$a=1;

$b=0;

switch($a) {

  default:

    $b += 1;

    break;

  default:

    $b += 2;

}

echo $b; //output would be 2

 

Should I report a bug?

 

Cheers,

Robert
