Is there a non-macro-based variant of the IDL in development, or is this 
referring to the implementation behind the macros?

If the first, sorry that I missed it.  Could you please give me a link?

I find all of these distrurbingly reminiscent of COM interfaces...

I beg to differ, and I am sure many others will along with me :)

My preference is for 'unknown', since you don't know anything about the type.

FuBar(unknown obj) {
   if (target_type(obj) == typeid(int)) {
     cout << extract<int>(obj);
   }
}
