You should read perlreftut, perllol, perlref, and perldsc... it'll take you a couple hours, but it will really help your understanding of references.

I know this is old, but the @value_array in the for-loop doesn't need to be created. I'm sure there's a lot more that could be cleaned up to make this closer to a one-liner (just looking at it), but I figured I'd update the most important part, due to efficiency issues with creating temporary variables in a loop. You can just reference an array's value like: `$new_hash{$key}[0]` Note: The example uses $_ instead of $key and instead of choosing the second element in the array (1), I've replaced with the first element (0).
