[Melbourne-pm] Facebook::Slurp, Filter::Self

[Drew Taylor]

I'm not in Melbourne (give me a few years), but I thought I'd put in my
€0.02.

You might also want to look into Moose and/or MooseX::Declare. Mx::D gives
you some nice syntax for defining methods and the parameters passed, while
Moose gives you a nicer OO interface.

Regarding source filtering, Just Don't Do It. Ricardo Signes' review of
Filter::Simple says it all: "Don't write source filters. They will make your
momma cry." Moose (or perhaps Devel::Declare if you want to go really
low-level) is a much better way to achieve the same effect and keep you
sane. :-)
