+       \item Flatten the grammar
+       \item It can propagate the multiple right hand side non-terminals by
+               remembering them. Instead of a single non-terminal as the result of a
+               production it can be multiple that in turn both have to fit when
+               parsing new words.
+       \item Remember from which rule a rule origins as a way of keeping back
+               pointers.
+       \item At some level the algorithm can already check whether the entry is
+               possible at all by peeking at the word. In this way a lot of trees can
+               be pruned as it is clear from the beginning that an \emph{NP} can never
+               start with a \emph{Verb}
