I can't find any email answering this question:
perldoc perl OR
perldoc perltoc
isn't it so obvious! :) You can also find out about modules in
this same way, e.g.
perldoc strict
perldoc Data::Dumper

You point have a point there, most of the people who reply
to beginner questions are Perl experts. Some are even
perverse enough to enjoy using references, slices and
anonymous datastructures whenever they could be useful.
[If none of the other experts recognise these traits as their
own, it is because I refer mainly to myself :) ]
Of course, the best ways to hone your skills is to avoid
repetitive programming tasks, and help either by trying
to answer questions here or joining in the fun by writing
modules for CPAN.

$questions_asked{bryan}++; # It's another question! :)
To get this to work, use the following:
$lines[0] = [ "dog", "cat" ];
print "@{$lines[0]}[0,1]\n";
The precedence of just a @ is by default:
@{$lines[0][0,1]}
which answers the problem others have been experiencing.
Take care,
