+1 — yes, please!

Yes, this is a big cleanup of mental overhead when accessing class/static properties and functions that are related to the instance. This avoids the need to confirm, each time you read it, that the name of the receiver is the same as the name of the containing class/struct/whatever, as well as avoiding subtle bugs when refactoring code.

Yes, this helps avoid bugs, and shows clear intent. The name of `Self` shows the clear relationship between that and `self` where `dynamicType` does not.

No, but I’ve certainly been annoyed by its lack in other languages…

A close reading of the proposal and associated threads.
