Re: [swift-evolution] Generic Subscripts

Okay, I agree that throwing subscripts would be great to have. Likewise, generic(and maybe even throwing) properties could be useful. However, I think that for this proposal, it makes more sense to focus on just generic subscripts, and mention throwing subscripts as "future improvements"? On

This particular case doesn't quite relate to the URL literal/regex discussion, which would require a complex new static evaluation feature. For this, the compiler *already has* logic to determine whether a string literal is

As Rob Mayoff pointed out, you can use MODIFIER LETTER PRIME - or PRIME, DOUBLE PRIME, and TRIPLE PRIME - which makes more sense than an apostrophe. Now if only there were a keyboard that had a touch-screen at the top which could be used for typing context-sensitive characters that would otherwise

Re: [swift-evolution] Consolidate Code for Each Case in Enum

I like the idea behind this, but I think the proposed syntax abuses extension, which applies to types not individual cases. Putting the code outside the enum also seems wrong, and it’s difficult to see how the compiler would handle it, in particular ensuring exhaustiveness. So I have come up with

Re: [swift-evolution] Best way to handle escaping function that might throw

Another possibility, other than generics, would be to drop rethrows all together and have the compiler infer if a throw is possible or not, including: struct FStore { let f: () throws -> Void func call() throws { try f() } } The compiler can make two versions, one if f

Wouldn’t protocols be a better solution in this case? If little to no logic can be shared between enum cases, why have the enum in the first place? Your variant: protocol State { mutating func react(to event: Event) } enum AuthenticationState: State, CustomStringConvertible { case

Re: [swift-evolution] Allow ' in variable/constant names?

It's not as easy to type, but you can already use U+02B9 MODIFIER LETTER PRIME for this purpose. Swift accepts this: let x = 1 let xʹ = x + 1 let xʹʹ = xʹ + 1 let xʹʹʹ = xʹʹ + 1 On Wed, Jan 11, 2017 at 7:08 AM, Tuur Anton via swift-evolution < swift-evolution@swift.org> wrote: > I often have

You are just going to drop this entire project, that has its name associated with you, for a very fierce competitor? However capable Ted Kremenek is, and I am sure that is, you have collectively decided to break this programming language every year or so. Who is going to get behind this

Re: [swift-evolution] Consolidate Code for Each Case in Enum

I'll summarize my thoughts for now, after thinking about it for a bit longer: Plusses: + In some cases it's nicer to have the ability to group functionality at each case rather than spread across methods lower in the type definition. I've written enums that were like state machines where being

Interesting proposal Tim. So instead of repeating the enum cases multiple times we repeat the functions multiple times? I feel like this merely flipping the complexity but not really getting rid of it. On Tue, Jan 10, 2017 at 8:08 PM Tim Shadel via swift-evolution < swift-evolution@swift.org>

I guess you don’t like Swift then after all? In my humble experience I have been involved in writing iOS apps since 2008 so seen a few changes - I have found it quicker and easier to write in Swift and just get things done better ( compared to Objective C ). For me - Swift is most welcome,
