yeah, I know :-)

I'm doing that inside synopsis right now, i.e. I'm adding tests
to the opencxx backend inside synopsis. My tests are all organized
using the qmtest framework (www.qmtest.com), and I offered Grzegorz
to put something similar into place for his project.
That being said, I still hope (as you may know) that we can at some
point merge both projects. Right now I'm doing most work on synopsis,
offering from time to time to merge back fixes into the OpenC++ project.

I'm just starting my work on the backend. My plans are (in that order):

* rewrite some low level classes (Buffer, Lexer, basically)

* make the existing API more clean (const-correct, more typed, etc.)

* try to understand how the Parser needs to be changed in order to
   correctly understand the tokens, i.e. build a correct parse tree / AST
   (see recent posts on the opencxx list).

* build a true high-level AST API on top (no more Car() / Cdr() calls !)

* export that AST API publicly through C++ as well as python

* get rid of the occ executable, provide a python script instead (for
   backward compatibility only)

* solidify the C++ / python APIs to let users build their domain-specific
   applications either as python scripts or C++ programs

I realize this is a lot of work. I'm not sure what the timeframe is to get
all of this done. I'v almost finished the first point (the Buffer is committed,
the Lexer will follow one of these days).
If you are interested in getting involved, let me know.

Kind regards,
		Stefan
