With the locally installed version of Moose (2.1404) I get no error or warning if I use the with method but specify an unloaded package as the role name. I had simply omitted the "use My::Role" before trying to specify a class and define it using "with'My::Role'". The class compiled and executed without any error, giving no complaint until I actually tried to use a method that was provided by the role and the method was not found.
Is there some important benefit in having with accept a role name that does not exist? I took a long time to find my problem because the with was "obviously" succeeding without error in linking to my role, so I was tracking through all sorts of later stages until I worked my way back to this root cause. If there is some value in specifying a role that has no content, perhaps there could be some syntactic designation for such cases, so that an error message could be issued for a role that *is* expected to supported by a package when no package is found to provide that role.
