Unfortunately, I was disappointed to learn at YAPC::NA this year that MooseX::Declare is frowned upon. I wouldn't say that. Yes, I'm familiar with Stevan's ... erm, distaste, shall we say? ... for MXD; I just disagree with it. And to say all Devel::Declare modules are bad is going too far, IMHO. MXD does have some pretty damning issues, though. Happily they can be addressed by using Method::Signatures::Modifiers.
