imho the current situation is an anti-sweetspot:
It lacks the elegant simplicity of the original model, but still isn't powerful enough for many things.

Yes — and I would really appreciate if not only this topic is reviewed with the added experience of real-life usage of Swift.
Maybe there are some things that are to basic even for the list of commonly rejected proposals*, because they are either unthinkable or seem to large for the evolution process (there is a strong preference for proposals that are only small refinements for the language, so it is easy to lose sight of the big picture).
I wouldn't expect actual changes triggered by such a discussion, but I'm also very interested in getting to know the motives of fundamental decisions that happened before Swift went Open source.

* Things like:
- Are Repeat-While and While-loops really necessary? I bet many never use them
- Why are optionals modelled as enums? Union types have some nice characteristics for this use case
- What's the point of enums with associated values anyways? Aren't case classes nicer?
