change in the API for literals
...
The API in the C runtime as well as in the Haskell, Python and Java binding
is changed. Now instead of adding the literal callbacks to the concrete syntax
you need to supply them every time when you need to parse. The main reason is:
- referentially transparent API for Haskell
- when we start using memory mapped files we will not be allowed to change
anything in the grammar data structures. At that point the old API would
be impossible to use.

a partial support for def rules in the C runtime
...
The def rules are now compiled to byte code by the compiler and then to
native code by the JIT compiler in the runtime. Not all constructions
are implemented yet. The partial implementation is now in the repository
but it is not activated by default since this requires changes in the
PGF format. I will enable it only after it is complete.
