Yeah, it would be cool to be able to do what the AppleScript Studio 
folks do in other languages.  I don't know how this works, however, so I 
don't know how easy it would be to retool...

Yes that's probably right.

I see...  The new version of SWIG looks pretty nice, particularly for 
wrapping C++ stuff (you can generate little Class factories, and then 
the methods hang off the created objects, which is convenient).  He says 
there is also support for ObjC, but I didn't see any docs about it.
