Erlang module for SWIG?

while SWIG has its own interest, perhaps you might find the route
useful that Daan Leijen has chosen for creating the Haskell binding
to wxWindows:

  "Since the core interface is generated automatically from the
   wxEiffel binding, about 75% of the wxWindows functionality is
   already supported, excluding the more "exotic" widgets like 
   dockable windows and the openGL canvas. .."

   wxcore [documentation]. The Haskell binding to the core wxWindows
   library. This is just like programming the wxWindows library
   directly, you can see some examples in the cvs. All the method
   definitions and marshaling code is generated automatically -- about
   500 classes with 2500 methods and 1000 constant definitions. wxcore
   uses the following two sub-projects: 
   wxc. A C project that puts a C wrapper around the C++ interface to
   wxWindows. This makes it much easier to access the wxWindows library
   from Haskell. The C wrapper consists of the C sources of the Eiffel
   ewxw library for wxWindows. We also added a few files to make the
   project suitable for Haskell, but we made no changes to the original
   Eiffel sources. This way, we are able to automatically update the
   sources from their cvs server. A big thank-you to the people that
   worked on the Eiffel library! 
   wxdirect. A Haskell program that reads the C header files of the
   wxWindows C library and automatically generates Haskell marshaling
   code and class definitions."

Erlang and Haskell FFIs differ, and I don't know the details of
this, but perhaps you find useful info there..
