Re: Perl 5.12.2 Data Structures

For your local installation (if it's more or less standard), invoking
    perldoc perldsc
(or any other documentation module) from your friendly, local command line should get you the doc for your installed version. For the on-line documentation, there's a  Perl version -> Select drop-down in the top left corner of the page. Available versions go all the way back to 5.8.8.
