+>>> Yes, the idea was to allow the file to be parsed as YAML, you're right. I just found that I tended to have problems when people used "---" for horizontal rules. However, I have also found that trying to keep it solely as an IkiWiki directive doesn't work either, since sometimes the meta-data I need also contained "]]" which broke the parsing of the directive.
+>>> So I have decided to go for a compromise, and make the delimiter configurable, rather than hardcoded as "---"; the triple-dash is the default, but it can be configured to be something else instead. I haven't pushed the change yet, but I have written it, and it seems to work. -- [[KathrynAndersen]]

+>>>>> Since I allow all legal YAML, the only way to check if it is legal YAML is to use the YAML parser, by which time one is already parsing the YAML, so it seems a bit pointless to check before one does so. -- KA
