-1, because it's already easy to add singleton methods and/or build 
proper wrapper classes with delegation - and the latter is usually a 
better solution longer-term (*)

I do think that << should be more widely implemented: e.g. in Proc as an 
alias for #call, and in Hash for 'add [key,value] pair', so it becomes 
more useful for duck-typing. But I don't think that's the point you're 
trying to make here.

Regards,

Brian.

(*) For example, the 'entries' proxy you return currently only 
implements #<<. What if you later want it to implement #size or #empty? 
or #first or ...

Also, objects with singleton classes cannot be marshaled.
