I've investigated why jbofi'e doesn't reduce ca'a to a standalone term (inferring 'ku') when 'pu' is the lookahead token. Essentially, it's because it thinks it's starting to see something like mi ca'a pu gi le nanmu gi le ninmu cu broda (whatever that might mean), i.e. it's expecting to see 'gi' after pu to make everything work out OK. This expression parses OK on the official v2.33 parser. (I don't actually have the official v3 parser running yet - I've never got round to sorting the build out.) I need to away and think quite hard about this problem. The full extent of the bug is not yet clear to me - I presume I'm missing one of the pre-parser stages that the official parser has. It's certainly pointing to a need to press on with building the official v3 parser & the random sentence generator I half finished, so I can start smoking out other corner-cases like this one. -- Richard. ---------------------------------+------------------------------------- Richard P.
