I'd love to have a GNU Python compiler. If this project is still active, I'd love to help.

I need one

Implement gpython.h and lang-calls.h which holds only whats needed for the compiled language calling into runtime. Make more explicit interfaces and helpers.

Need to implement exceptions fully Python >= 2.5 support is hard to write the grammar for so implement the 2.4 python style is simpler and more doable for now.

Reuse C++ native exceptions at compile time and link in some c++ exception handling code or figure out how they are implemented and use /setjmp or set/get context

Seriously awesome project. Using the example code at http://gcc.gnu.org/wiki/gccpyinstall (with or without commenting out the print statement in foo2.py).

$ cat Makefile
all:
gccpy -O0 -fdump-tree-gimple -fpy-dump-dot -c foo2.py -o foo2.o
gccpy -O0 -fdump-tree-gimple -fpy-dump-dot -fpy-gen-main -c foo1.py -o foo1.o
gccpy -O0 -o test foo1.o foo2.o

clean:
rm *.o *.gpyx *.gimple *.dot

$ make
gccpy -O0 -fdump-tree-gimple -fpy-dump-dot -c foo2.py -o foo2.o

We need this to work correctly.

Make a sys.py module for the python stdlib

Doing something like:

x,y = 1,2

Doesn't compile its something i don't like very much and will leave it to later milestone.

The access to globals and other memory need a cleanup to maintain consistency across code generation

There isn't one.

need to implement the builtin python sys module

Dicts need implemented

We need this to work correctly.

Just an outstanding tool. It would be great to know upfront how feasible compiling things like system libraries, (simple)json, socket libraries, etc will go. If it's possible to completely compile a REST/http server, for instance, that would be absolutely outstanding especially when looking at all of the options out there (psyco, etc)

Also whether there are any differences between Python 2.x and 3.x when using the tool.
