hi Oleskii,

Sorry for the delays.

Yes, I agree that the current implementation is not satisfying on this
regard.  IMHO, the %destructors should be called when an exception is
rised, exactly as if the parsing was ended on a syntax error.  Would that
match your expectations?  Would you be ready to try patches we might
submit?
