in thread Noble DOT vs the Allmighty ARROW

Not to be picky (because I might be terribly wrong), but I believe the actual concatenation operator is space underscore space.

So, BUU's code would change from: 

blah blah"_$d->func_"somestuff";

[download]
to 
blah blah" _ $d->func _ "somestuff";

[download]
Minor change, I know. But, I really don't like the change of the concatenation operator. (I am just hoping I am remembering the Apocolypses correctly. UPDATE: I did remember correctly. Here, he talks about whitespace surrounding operators.)

And, I use the dot for string concatenation a lot too, BUU. I wish it weren't changing.

    I don't like it either. But on the plus side, you will be able to use the hyper concantenation operator. 
    print _("Blah blah",$d->func,"somewhat");

    When perl6 makes it's debut, I will probably use this form exclusively. It's too hard to tell at a glance between $foo_bar and $foo _ bar on my screen.

      Nifty, I didn't know about _(). Although the example might be better put 
      $string = _("Blah blah",$d->func,"somewhat");

      [download]
      since 
      print "Blah blah ", $d->func, " somewhat";

      works today. What I am worried about is not $foo_bar vs $foo _ $bar but rather the later vs $foo - $bar. When we used the . operator a mis-shift would result in $foo > $bar which is easily seen even when you are skimming code.

        Duh. You're right, bad example.

    Just think of how much this is going to cost in terms of Perl Golf characters. At the same time, though, aren't they running out of punctuation-type character operators found on the regular 104-key keyboard?

    It is odd that period is used as an operator at all, really. Syntax wise, the fact that a scalar is both a string and a number complicates things somewhat. Still, why not something more abstract? Here's some useless ideas: 
    $foo = $bar:$nuu;    # Currently meaningless
$foo = $bar'$nu;     # Ye-olde ' operator?
$foo = $bar<->$nu;   # Maybe?
$foo = $bar$nu;      # Or nothing at all?
$foo = $bar $nu;     # Implied?
$foo = $bar~$nu;     # Getting kind of crazy with overloading

    Still, this "space underscore space" stuff smells of Python-like schenannigans.

    I'm half-inclined to start a campaign to develop an alternative.

      I really don't want to have to try and parse 
      $concated = $x < $y ? $x:$y : $y:$x;

      I think the ' _ ' operator is ugly, but not that bad. In general I don't think there will be much call for it in the future since we will be able to say things like 
      $string = "for $x + $y the answer is $($x+$y)\n";

      [download]
      instead of 
      $string = "for $x + $y the answer is " . ($x+$y) . "\n";
