Because I had little need for it I had tried to just ignore Perl's
Unicode support as long as possible. Now it looks like I can't do that
anymore, so I started looking through the various docs.
One thing that confused me: several sources mention Perl using 8-bit
characters as long as possible, whi
I have this statement;
foreach my $key ( keys %filehash ) {
print "$key $filehash{$key}->[0]\t\t\t$filehash{$key}->[3]\t
$filehash{$key}->[2]\t $filehash{$key}->[1]\n";
}

do I do this?
I can't make a separate hash of t

Not in my book. The command line switch turns on warnings globally, whereas the "use
warnings;" pragma only enables them in the current lexical scope. So by using the
command line switch, I ge

(CEP) application and I would like to do the same in perl that is my
favorite language.
