Yes, I tried using SWIG. I thought it would be of great help.
Unfortunately some functions in the 2.25 api are rather difficult (or
should I say almost impossible) to implement using SWIG. For example,
the Blender.Get function can return an integer, float or a string
depending on the argument you pass to it. If you check the history of
the BPY_interface.c file in source/blender/python, you'll see when I
stopped using SWIG:
