It's interesting the lack of round tuits these days.

My list of modules is currently:

• GD
• Soap::Lite
• LWP
• GnuPG
• OpenFrame
• Tk for anything apart from trivial apps

That's just for starters. I could probably thing of many more.

My attitude to modules is to learn and use them on an as-and-when required basis. This does mean I have to expend time searching to see if I am re-inventing the wheel before putting finger to keyboard, but it means that my appreciation of modules is from a practical standpoint - and this is changing as I look at how one prepares modules for CPAN publication.
