Why are you so sad ? this was not in the purpose to pretend there is a "problem" (except that I suspected an error). I was just curious beceause I used to read that Ada and Pascal are exemples of unambigous grammar. As well, about LR(1), this was not to use it as a reference of readibility, beceause the humain view of a text is not based on a LR(1) analisys. A grammart bay be LR(1) while not redable, or the opposite. I was just curious and surprised, that's all.
