Hi, monks

Without loading any Perl modules, what is the fastest or best way to change key=>value pairs to value=>key pairs of a large hash. Assume no duplication in both key and value fields.. Many thanks

BTW. I am now using the following which looks dummy

  $hash1{$hash2{$_}} = $_ for keys %hash2;
