Re: Problem to store referrence as key value in a hash

[perladdict]

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";
}
