S12 describes a feature to call sets of methods at the same time: http://feather.perl6.nl/syn/S12.html#Calling_sets_of_methods
I would like the spec to clarify what happens to the return values of all these methods. I'm fine with a simple answer, such as that they are not available, or only the first or last set of return values is returned. As a "use case", we may use of basically this feature in CGI::Application in Perl5, as part the plugin system. Each plugin location is like a method name, and as we get to each point in the code, we look up through the inheritance tree, executing methods at each location. In this case, I think we ignore the return values. Mark
