Excellent, thanks! I need to up my archive searching skills...
Anyway, I think it might be worth it to extend the syntax to support more than just symbols. For my cases, symbols will do the job, however for example for externally defined (e.g. config file) key names it would be quite handy to have calculated string keys as well. How relevant is the object model reformation nowadays since we've decided that collections use get()/set() methods instead of accessors?
