You mean like with define_method? Something like this could also  
happen in ObjC anyway, using forwardInvocation: ... although that's  
really more like method_missing. In fact I think I even used it that  
way a few years ago :-)

Certainly it "looks" the same to the caller either way...

That would be awesome. Something like sdef/sdp for Ruby classes maybe  
those tools would be useful already.
