[swift-evolution] [Fake-Proposal] Remove enums with associated objects

[Tino Heth]

Damn, there seems to be no better way to create reactions than saying something stupid ;-) - to bad the reactions tend to focus on the stupidity in this case...
It should have been "union" instead of "sum", so basically having Optional<T> modeled as (T | Void)

> Enums in Swift *are* sum types. There are various ergonomic issues with their usability, perhaps, but any implementation of sum types would be different sugar over the same underlying semantic model.
