forget the soap what about this?

my $tp = new IO::File "Sharmen", "w";
$tp->wipe();
if($bathroom)
{
     SWITCH: {
     
     $bathroom eq "dark" && do { &lights('on');};
     $bathroom eq "stinky" && do { &fan('on');};
     $bathroom eq "leaving" && do { &lights('off');};
     DEFAULT: { &lights('off') && &fan('off');

     };
}
