Usually these kinds of errors occur when you've got some kind of 
illegal syntax in your grammar.

I *think* this one is where you've mixed an AST rewrite with a 
^-flagged left half.  (Or possibly it's the one where a rewrite is 
mixed with a !, but I think that one mentioned a different 
template.)
