Ah, then what you want is a switch like statement .
There's a module : switch .

Or you can do it in a great number of various ways, the most common one is using a named block with last:

SWITCH: {
      if (expression) { statement(s); last SWITCH; }
      if (expression) { statement(s); last SWITCH; }
      default statement(s);
}

update : don't try to be funky by using that switch module :) just use the if / last style ! See the answers by corion , holli and virtualsue !!
