The use of documentation.

In answer to you question on the use of documentation ...

I tend to grab for the Perl 5 Pocket Reference quite often. Sometimes I find myslef searching in perlfunc. Perl in a Nutshell get it's uses as does the Perl Cookbook. Even less ... Advanced Perl Programming helps me with LoL type problems. I don't find I need those advanced techniques all that often.

Advanced techniques? I use them all of the time, and the trick is that they are not very hard (at least not in Perl). For instance a hash of hashes? That is just a directory structure: `# Name it absolutely $foo{some}{path}{to}{the}{thing}{I}{want} = "something"; # Or relatively: my $h_ref = $foo{some}{path}; foreach my $thing (keys %$h_ref) { print "Found key '$thing' with value $h_ref->{$thing}\n"; }` [download] It is just an odd delimiter. shrug For the next trick look at map and grep and the general list-oriented nature of Perl and see it as a Unix pipeline written (unfortunately) right to left instead of left to right. Now stare at the Schwartzian sort and see why it is so natural. In no time these "advanced" techniques will feel like part and parcel of how things work... :-)	[reply] [d/l]

}
