in reply to Problem to store referrence as key value in a hash

In your example $key stores the reference as string,so you can't convert
string back to reference,it will not returns a hard reference.

There is one special kind of hash Tie::RefHash in which we can store reference as keys.
Below is the code i tried,it may help you to store reference as key in a hash.

use Tie::Refhash; tie %hash 'tie::RefHash'; %hash =( ["one","two"] => "numbers", ["pen","book"]=> "stationery"); while(my($keyref,$value)=each %h)) { print "@$keyref has $value\n"; }
