Re: [swift-evolution] [Swift 4.0] Conditional conformances via protocol extensions

I'm not very familiar with the runtime so forgive me – the protocols would only have to be added once right? And couldn't this usually be done at compile time, or does it happen when the module is linked at startup? On Thu, Aug 4, 2016 at 4:36 PM, Haravikk via swift-evolution <

[swift-evolution] [Swift 4.0] Conditional conformances via protocol extensions

In the generics manifesto (https://github.com/apple/swift/blob/master/docs/GenericsManifesto.md) conditional conformances via protocol extensions is under unlikely. The manifesto notes: "This is an extremely powerful feature: is allows one to map the abstractions of one domain into another
