Moo - almost, but not quite, two thirds of Moose
Matt S Trout will give a talk at YAPC::Europe 2012 described as
Moose is one of my favourite things to happen to perl in the last five years, but the startup overhead and additional dependencies can be hard to justify for very small projects.
So I asked myself ... "what's the smallest portion of Moose that I could
get by with, that would be easy to build so that when I load Moose my
classes can transparently upgrade themselves?".
The result is Moo - which provides most of the basic syntax of Moose -
and rather than trying to reinvent the MOP part, remembers enough to
make you a Moose::Meta::Class if you decide you need one later.
In this talk, I'll go over exactly which bits of Moose it provides, which
bits it doesn't (this list is longer :), why, and how it's built from
the ground up to be the right answer to "I want something smaller than Moose".
