Kevin Tew started investigating this ticket, and he discovered that :method subs are already being placed as entries in the namespace by default, which is the behavior I was looking for. So, the issue turns out to be a non-issue (for me at least), unless we decide to make it one.
Apologies for the false alarm. I'm not sure what led me to believe that :method subs weren't going into the namespace, as I can't reproduce the problem now. We can either rename this ticket as "provide a way for :method to not appear as namespace entry", or we can just close the ticket. I'm in favor of the latter for now. Pm
