You have a good point! It was quite a bit work to convert the grammar from c
to java (at least for one like me who knows no antlr nor c). That should
teach me to keep the grammar as language independent as possible. Maybe the
best alternative would be using only antlr constructs if possible, and if the
readability is not that good, just write an explanation in a comment
