in reply to Migrate your perl project to Moose
I've read a number of tutorials and used Moose on a couple of projects. Learning the basics are easy, figuring out the right way to do more complex things is hard.
Roberto Signes' excellent workshop slides, "Moose is Perl" helped a lot in understanding advanced topics in Moose. I only wish he would turn it into a text article or book, rather than mere PowerPoint slides.
