"Learning Perl" does not cover references and complex data structures.
"Learning Perl: Packages, Refrences, Objects and Modules" does.
Programming Perl is not really a tutorial. Perl in a Nutshell is more of
a reference. Perl Cookbook contains more complex recepies.
The chapter below contains exactly what you need under "Hash of hashes" as
does the perldsc man page. I'd recommend reading the Beginning Perl
chapter as its better written.
