Has any thought been given to adding Object#__noSuchMethod__ or the like
(propertyNotFound, method_missing, or whatever it would be called) in

I ask because another commonly requested feature, mixins, is easily
implementable in terms of noSuchMethod and getters/setters.

I'm not sure about the implications for implementors or performance
(noSuchMethod probably requires a second method lookup pass; I'm not sure
how much overhead method lookup has in JS), but being able to override
method dispatch itself via a mechanism like this is very powerful.
