Don't do that with split(), (please)

split() works as follows ( I know it may work the way you have it but.. well... that's just wrong: 

split /:/, $passwd_line;
split '', $line; # 'Special' case
Thanks,

    To what, in particular, are you refering?

      I'm refering to splitting on a scalar value such as the following wrong way: 
      split "\n", $line;

        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.
