I've updated the sample Scheme implementation to use the new BNF production after ".". It passes all the tests and seems to work well. So I think we should use the updated BNF, with the new "post_period" production, so that we can cleanly handle special comments after ".". I haven't heard anyone speak up about the utility of the ". $" construct, so I intend to remove it from the BNF and sample implementation unless someone speaks up ASAP. After that, I plan to post an updated SRFI-110. --- David A. Wheeler
