  I certainly don't agree with replacing "if else" with "? :". You throw your readability out the window, IMO. But I guess that is what makes it "extreme".

    Each has it's use in it's place. Use "? :" when you need to return a value in a statement inline. E.g.,

    my $x = $test ? $y : $z;
    # is better (disclaimer - IMHO) than:
    my $x;
    if ($test) {
      $x = $y;
    } else {
      $x = $z;
    }

    All of the examples of "? :" in that document (that I can see) are similar to this, so they're ok. Using "? :" in a void context is arguably not so good.

      my $x = $test ? $y : $z;

      I can understand doing the above becuase visually you can isolate that line and grok it quickly. When you use it in a larger "else if" context you loose that visual recognition.

        How about:
        
          my $foo =   ( $bar =~ /pattern/ )
                    ? ( some expression )
                    : ( some other expression );

          I do something very similar to this in my code on a regular basis - What I normally do is shift the ternary operators back onto the leading line so that it is immediately apparent that the line has not ended. For example:

          my $foo = ( $bar =~ /pattern/ ) ?
                    ( some expression ) :
                    ( some other expression );

          This of course is more of a question of style than anything else, and I know that I am somewhat obtuse and anal at times with regard to my layout style.
