And that's the hard part. Everything else is just tedious.

I don't believe it is. I just tried it. This alone would be big win in 
terms of fighting source code bloat. No need to wrap C functions in 
Scheme procedures that do nothing but set a finalizer. But you're 
probably well aware of the benefits, since you suggested the function 
in the first place.

While I have you here, I was wondering if there might be a way to use 
SWIG to generate Chicken procedure names with characters other than 
[0-9A-Za-z-] in them. Specifically, I'd like to stick some colon in the 
names e.g. "data-type:operation-name". Is there a way to do this in 
SWIG?

Thanks,
