in reply to What are all the false values in Perl ((conditional, boolean, whitespace, unprintable characters)

I agree with swift -- print length($string) if you're not sure... and as for printing "unprintables":

sub literal {
  require 'dumpvar.pl';
  &dumpValue;
}

The dumpvar.pl library is, in fact, what the debugger uses when you tell it x $string.

$_="goto+F.print+chop;\n=yhpaj";F1:eval

One can always make use of Data::Dumper if you would prefer modules to libraries.

Yes, by setting $Data::Dumper::Useqq to 1.
