I just made this small piece of code to entertain my fellow monks. Guess what are the results from the last two lines (Tomorrow is a holiday, remembrance day, in Canada, so happy holiday, is it also a holiday in some other countries?): 
my @a = ();
$a[0] = \@a;
my $expr = '$a[0]';
my $index;
for ($index = 0; $index < 1000; $index ++) {
    $expr = "\${$expr}[0]";
}
print $expr, "\n";
eval "print $expr";
