1. If it's short, use the trailing if ... 
    my $bar = "true" if $foo;

  2. If it's short and you have two options, use the trinary operator ... 
    my $bar = $foo ? "Winner!!!" : "Please play again.";

  3. If it's a longer block, it doesn't matter if you have one declaration line at the front. You can even use default values if you want. 
    
my ( $foo, $bar, $baz, $wumpus );
# or
# my ( $foo, $bar, $baz, $wumpus ) = ( 5555, "Blossom Garden Rd", "San
+ Jose, CA", 95123 );

if ( $tiddly_rump ) {
    $foo ....
    $bar ....
    $baz ....
    $wumpus ....
}

    That's not so bad, is it?
