Indexing access for Lists and Maps considered harmful?

[Shams Mahmood]

I don't follow why it won't handle anything other than the collections api.The compiler should be able to support any implementations of IndexedAccess<V> and DictionaryAccess<K, V> just like the for each loop handles any implementations of the Iterable interface.

The link to methods in Collections is a bit too magical (e.g. it won't gracefully handle anything other than the collections API nor will it gracefully support evolution of the platform).
