If SWIG works for Python, then it should work for Go.
The SWIG code is not yet finalized, but it is close. It has been
committed to the swig SVN repository, but there is still a bit more
tweaking before it can be considered finished.

Oh, you can certainly try it now. In fact, I would encourage you to
do so, and report any problems that you find. The details which
remain are things like the precise names to use in the generated
