These are the modules that I reach for first when trying to solve a problem:

• Scalar::Util
• Scalar::MoreUtils
• List::Util
• List::MoreUtils (This is just a phenomenal module)
• File::Slurp
• DBIx::Class
• Catalyst and, possibly, CGI::Application
• DBM::Deep
• Test::Deep, Test::Warn, Test::Exception, DBD::Mock (numerous others in this category)
• Set::*
• Algorithm::*
• Tree
• Template Toolkit, Excel::Template, PDF::Template, CAM::PDF, Test::PDF
• Moose

And this is just what I can think of in 10 minutes. Some of them are written/maintained by me and most have been contributed to by me or people I know. In addition to this list is a knowledge of how to navigate CPAN and whom to ask when I want to solve something.
