cpan modules to go through

sathiya.sw has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

Can anyone please, give a list of good modules to go through in CPAN ?

I believe by doing code walk through of some modules in cpan would enhance my Perl knowledge. So can anyone please list out some of the modules which are good in all or some of the following aspects.

perl programming.
dbi.
sockets.
debugging.
object orientation.
data structures.
And other important perl features.

Would be thankful to see the replies with some good module names.

DBIx::Class comes to mind, it meets at least four of your criteria. But then I doubt that reading quasi random foreign code helps you greatly improve your programming skills. A much better approach is to write code yourself (and read the documentation if you don't know any further, and ask here when reading the documentation does not help).	[reply]
