Subject: Little switch improvement: get the used variable
From: martin.keckeis1@gmail.com (Martin Keckeis)

Hello together,

i often write switches, where i throw an Exception when something unknown
come in, rather than using a default value.

switch($myVar){

  case 1:
    doSomethingElse();
    break;

  case 2:
    doSomething();
    break;

  //...

  default:
    throw new Exception('Undefined input: ' . $myVar);
    break;
}


I would like to write something like this:
switch($myVar){

  //...

  default:
    throw new Exception('Undefined input: ' .
get_the_used_switch_variable());
    break;
}


The `get_the_used_switch_variable()` is just a placeholder, name can be
changed to something natural...maybe a constant.

It's really usefull, when dealing with nested objects like when you work
with Doctrine.


Best regards
Martin
