Code:
2 + 2 x 2 = 2 + (2 x 2) = 2 + (2 . 2) = 2 + 22 = 24

How'd I do?

I knew there would be... but someone had to state the obvious , right?

I guess 'x' is not multiply.

exactly, it can work with full strings as well.

Code:
print "spam!" x 3;

hmmm, handy, I think. Maybe good for those lengthy nbsp; lines or for drawing text graphs perhaps!

It's an odd one, I haven't ever used it in my code yet, but I'll bet it's handy if you want to make dividers for sections in an email or reports for dot matrix (shiver) printers.

I was hoping this would work, i'd find it quite useful, but due to efficiency concerns, i guess not :(

Code:
$i = 10;
sub pickle { $i++ }
print pickle() x 10;

Code:
my $i = 0;
my $ch1 = '>';
my $ch2 = '<';
my $tab = ' ';

print "Content-type: text/plain\n\n";

for (0..20) {
if ($_ < 11) {
print $tab x $_ . $ch1 . "\n";
next;
}
print ( $tab x (20 - $_) . $ch2 . "\n" );
}

Or for things like that Cool

Code:
my $pickle = sub { return ($_[0] x $_[1]) };

print header();
print $pickle->('>', $_) for (1..10);
