That seems reasonable.

For Ruby they would only be useful where you want to mixin different
modules with identical methods, while needing access to a specific
access to a particular module's method that would otherwise have been
overwritten. Apparently this is such a rare occurrence that no one
worries about it and/or works around it for those times when it does
occur.
Unless anyone objects, you should keep your "traits" package the way it
is, and those other traits will be referred to as "roles" in Ruby
(should anyone implement them and release it as a package and/or
integrate it into the Ruby core).
