in reply to "Secret" operators

You may be familer with the spaceship operator already (<=>). What about the Super Star Destroyer operator?

${-} <=$vader=> ${-}

Update: Now complete with TIE Intercepters!

    Ok, I tried it out and now I have some doubts...

    $a <=$b=> $c is equal to ( $a <= $b , $c), that one is easy...

    But what happens if I just use <=$something=>? Because printing that prints an equal sign, the contents of $something and another equal sign... I'm missing something, here...

      I tried <=$vader=> (and also <==>), but they are both syntax errors. That's why I added the TIEs :)

      That's the <> operator. =$something= isn't a simple scalar, so it's equivalent to glob("=$something="). On the other hand, <$something> means readline($something). (For special weirdness, <$ something> is the same as glob($something).)

      See glob, readline and I/O Operators in perlop for details.
