while(my($key, $value) = each(%hash) ) { print "$key =>
$value\n"; }
my($key, $value); while(($key, $value) = each(%hash) ) {
print "$key => $value\n"; }

case 1:
by decalring "my" we are making the variable local.
So you cant access the value of those variable from the
outsite of that block.
case 2:
here you can access the value of the code from the
outside of that code.
"my" is generally used to protect the variable from
mingling.
