Has any thought been given to adding Object#__noSuchMethod__ or the like (propertyNotFound, method_missing, or whatever it would be called) in ES3.1/Harmony?
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. -- Yehuda Katz Developer | Engine Yard (ph) 718.877.1325
