i'm looking for a way to have a block of code that is used to set some value 
 sub block {
   my $setting= 0;
   {
     $setting= 1;
     COMMAND;
     $setting= 2;
   }
   return $setting;
}
$result= block();

in the above example, $result should equal 1. everything that i thought would work either does nothing, is invalid, or exits the block() function

i just want to exit the enclosing braces. i could likely solve this using another function, but i'd like to avoid that.
