I will often use multiple shifts if I want to short circuit a sub when a non-true value is passed. 
sub foo {
  my $bar = shift || return;
  my $baz = shift || return '<p style="font-color:red">BAD</p>';

}

Again I'll note that this works only for non-true values, IOW if 0(zero) is acceptable then don't do this.
