Comment (by cactus):

 I've started working on this, and I have the simplest case (pattern-only
 synonyms) almost working, with most of the groundwork done for simple
 bidirectional pattern synonyms as well.

 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?
