[swift-evolution] Remove Failable Initializers

As ease of use and performance implications have been discussed, I would still like to see the question of consistency addressed:
In Objective-C, returning nil from an initializer is nothing special — it is a regular function that returns id (self in most cases).
Swift, on the other hand, is different:
Init-methods are void-functions in every aspect, with the irregularity that we can return "nil" (if the initializer is marked accordingly).
Am I the only one who has the feeling that this is a little bit odd?
What kind of method is a initializer in Swift?
