Hi there,
cross-posting this because it's relevant to both parties: this is to let you know that I've started implementing a Gambit [1] back-end for SWIG.
So far I have the simple example from the beginning of the tutorial working [2]. Of course that's only the tip of the iceberg but, getting there...
You, both Gambit and SWIG people, will likely hear from me soon with some specific questions.
In the meantime, if you have any thoughts, suggestions, or relevant pointers -- they are welcome.
