It works exactly as posted for me (well, I did add a backslash to the first call to Dumper). I'm using Moose 0.40 here, what version are you using? 
$VAR1 = [
          1,
          2
        ];
$VAR1 = bless( {
                 'somearray' => [
                                  1,
                                  2
                                ]
               }, 'MyClass' );
