Quick note: perldoc -q regex will use a regular expression to perform a search of the perlfaq pages you mentioned. For instance:
[cwinters@genesee cwinters]$ perldoc -q hash Found in /usr/local/lib/perl5/5.6.1/pod/perlfaq3.pod How can I free an array or hash so my program shrinks? ... Found in /usr/local/lib/perl5/5.6.1/pod/perlfaq4.pod How do I test whether two arrays or hashes are equal? ... Data: Hashes (Associative Arrays) How do I process an entire hash? ... What happens if I add or remove keys from a hash while iterating over it? ... How can I always keep my hash sorted? ... What's the difference between "delete" and "undef" with hashes? ... How do I sort a hash (optionally by value instead of key)? (etc.)
Not only is this useful in and of itself, but since the FAQ entries frequently contain references to other perldoc pages folks might not know about (perlbot, perlref, ...), it's a great starting point, too.
