Chintana Wilamuna has recently tried out Catalyst for the Perl StockTrader client:
This time however, I had slightly more time available so I started from Catalyst::Manual::Tutorial and boy, the docs are amazingly well written. Kennedy Clark has done a wonderful job with the documentation.
Well deserved praise for Kennedy's work on the documentation. I think many people who tried out Catalyst in it's infancy don't realize how far the documentation has come since then.
