Ahh OK I didn't check the documentation in Moose::Util ... =)

apply_all_roles($applicant, @roles)

This function applies one or more roles to the given $applicant The applicant can be a role name, class name, or object.

The $applicant must already have a metaclass object.

The list of @roles should a list of names or Moose::Meta::Role objects, each of which can be followed by an optional hash reference of options (-excludes and -alias).

but couldn't find a description for metaclass either, I suppose a package container for roles.

Just for a better understanding, where in your code did you assure that the $applicant already has a metaclass object?
