my $t; # intentionally undefined $k = $t; # undefine $k
Just for clarity -
This isn't "undefining" it is assignment of nothing to $k;
my $nothing;
print "\n\$nothing\'s Value: $nothing and \$nothing\'s length ". length $nothing;
my $somthing = 100;
$somthing = $nothing;
print "\n\$somthing\'s Value: $somthing and \$somthing\'s length ". length $somthing;
