Hmm... found an interesting article:
http://www.antlr.org/papers/LL-star-PLDI11.pdf
It describes some disadvantages of Packrat parsing, like problems with
debugging and error recovery. These are important for DCT, so I'll have
to perform additional research.
Yup, LL(*) is my favorite so far. As for debugging and error recovery
they are always a problem.
