 Great to hear that you're working on this!  Just out of interest, are you
 implementing ViewPatternsAlternative too?  Pattern synonyms become rather
 powerful when you can use pattern guards inside them, which is what
 ViewPatternsAlternative lets you do.

 > What's the correct protocol in this case? Should I mark myself as the
 owner on this ticket until I have my patches ready for submission for
 review? Or only after an initial working version is accepted?

 You can assign the ticket to yourself if you're working on it, yes.
