I'm trying to make some proxies for MysterX (COM classes) in a quick  
way, for rapid prototyping. If I had that functionality I could just  
implement the forwardInvocation: method and just change that method  
call to a COM method call. And then incrementally making the objects  
more Scheme-like and rearranging the interface.

I hope that paragraph isn't very confusing ;-)

Hmm. Any docs on reader extensibility or must I read the code? Also,  
where is that stuff defined, I couldn't find it :s

Thanks
