Re: [rules-dev] RFC: declaration syntax

Just to explain how the parser recovers from errors, it tries to skip a token that fail to match the construct being parsed. If that still fails, it will skip all tokens until it finds the start of a top level construct (i.e. a statement like a rule, query, declare, etc) and resynch from there. If you have too many different top level keywords, it increases the probability that there will be a keyword clash and it will fail to resynch, resulting in cobolish errors for the rest of the file... :)
