Although if someone can start sooner than by all means, go for it! And obviously help would be great since it isn't a puny codebase (4,000 lines so far for the CST->AST and AST->bytecode code).

And obviously knowing a little more about the AST branch would be helpful for those considering helping.

Is there any relatively up-to-date document about ast-branch? googling about it turned up some pypy stuff from 2003, and I didn't look much further.

I just built the ast-branch for fun, and "make test" mostly worked. 8 tests failed: test_builtin test_dis test_generators test_inspect test_pep263 test_scope test_symtable test_trace 6 skips unexpected on linux2: test_csv test_hotshot test_bsddb test_parser test_logging test_email I haven't looked at any of the failures in detail, but at least test_bsddb is due to missing development libs on this system

One more thing: The software I work on by day has python scripting. One part of that functionality is a tree display of a script. I'm not actively involved with this part of the software (yet). Any comments on whether ast-branch could be construed as helping make this kind of functionality work better, faster, or easier? The code we use currently is based on a modified version of the parser which includes comment information, so we need to be aware of changes in this area anyhow.

(on the other hand, I won't hold my breath for permission to do this on the clock, because of our own release scheduling I have other projects on my plate now, and a version of our software that uses a post-2.3 Python is years away)
