Actually, i was looking for the same thing a while ago (didn't find anything)
i'm a bit surprised that everybody's soooo against thing thing. i, for one, have a Tk script littered with 
sub bar
{
  $foo = askFor( title => 'Name:' );
  return undef if not defined $foo;

  $baz = askFor( title => 'Cigarettes:' );
  return undef if not defined $baz;
}

[download]
stuff. &askFor simpy pops up an entry form that offers a 'cancel', which MUST cancel the caller (&bar), so for me a double-return would be great. (a significant portion of my code is starting to be this dumb "return if .." thing
but i always remember that i started of with BASIC, and am therefore not able to grasp the horrendous evilness of this (someone once pointed out that a double return would be a GOTOism (which would be bad)).
could someone explain why this would lead to spaghetti code, and other nasty stuff?
(i'm really afraid that i'm doing things now that'll make me loose my hair in a week)
