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...

      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.

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

[stevieb]: LOL you can easily replace "Helsinki" with "Alberta"
[perldigious]: I used to live at the top of a very steep hill stevieb, I can relate to the video. Literally used to have to build up momentum and try to force my vehicle to make it up the hill to park in my driveway properly... didn't always make it.
[choroba]: Why don't they use tire chains?
[perldigious]: First snow, probably not prepared right away choroba.
[stevieb]: it's Quebec... they do weird stuff there :) In the mountains, it is *mandatory* for trucks to use tire chains. Many passenger vehicles do as well (but it's not mandatory for them)
[perldigious]: That stuff can hit fast... like what we just got where I'm at. Saw a few people who had slid OUT of the roundabout I have to drive through to get to work, not used to the ice yet, take awhile to get the hang of it again and make vehicle adjustments.
[stevieb]: man, when the roads are glare ice, I don't even bother going to work or out... unless I absolutely have to, or was already out in the first place
[choroba]: Tire chains are mandatory here in mountains, and the only unprepared each year are gritters
[stevieb]: I have a 3 day winter survival kit in my vehicle in the event I get snowed in in the mountains (which has happened before due to avalanches closing the roads (and once in the summer due to a massive forest fire that trapped us
[perldigious]: a handful of people in my work area did not make it, but I live pretty close and it's flat the whole way, so I didn't have any trouble. The roundabout is the worst thing I have to negotiate.
