in thread Looping through a split() and more...

How about split '\n', $line;

That's still splitting on a pattern, not a literal. Quotes are only special to split in those cases described in perlfunc, otherwise they are regex delimiters.

The same holds true for the rhs of a '=~' expression. 

chh@scallop chh> perl -le '$a="foo\nbar"; print $1 if $a =~ "\n(.*)"'
bar
chh@scallop chh>

It's potentially misleading but not wrong.

    It's obsolete, in there for backward compatibility.. go read USENET, you'll see what I mean.

      Is it better not to use a literal string as the first argument to split(), especially when demonstrating functionality to new users? Yes.

      Is that functionality likely to be omitted from Perl 6? Possibly, unless that means forcing people to do silly things like this: 

      $pattern = qr/[:|]/;
@array = split $pattern;

# instead of

$pattern = '[:|]';
@array = split $pattern;

      Is it officially deprecated? No.

      Is it valid Perl? Yes.

      Should someone vote down this whole friggin' thread? Yes, please.
