in reply to Moose role with requirement consuming another role

I don't quite understand your approach. If role Role::App requires the attribute gazpacho that role App::FixIt provides, why not not simply compose App::FixIt into Role::App?

    My second example (with gazpacho), was really just meant to show that I understand the importance of the with/has order when a class consumes a role. Perhaps I over-emphasized it.

    The real problem is not with class<-role(requirement), but, similar to my first example, class<-role<-role<-role(requirements). Or to go into yet more detail, I have about 30 app classes which consume one of two specialized App roles, these both consume a generic App role, which consumes three further roles, MooseX::Getopt, MooseX::SimpleConfig plus our own app-logger role.

    I can easily drop the requirement in the app-logger role and everything works fine. I'm just curious if there is a better solution.

[ambrus]: Discipulus: I'm not sure, but it certainly doesn't suck as much as it's used to. it's like C++, it sucks because people still recursively learn from twenty year old PHP examples,

[ambrus]: I'm not trying to recommend PHP, but I think it has way too bad a name because of its past.
[ambrus]: This is different from MS Word, which was already a good editor in the pre-unicode days (in word for windows versions 2 and 6, which ran on windows 3 but also on windows 95), only it wasn't trying to solve the task of writing maths papers back then.
[Discipulus]: ah ok, sounds reasonable; with no fear: Perl all life long
