Re: [swift-evolution] use standard syntax instead of "do" and "repeat"

-1. Doesn’t seem worthwhile. There aren’t that many use cases were your code gets littered with try and it is nice to identify exactly what is throwing. Sorry, — Howard. > On 4 Jan 2016, at 2:52 PM, Andrew Duncan via swift-evolution > wrote: > > >> On 3 Jan, 2016, at 10:51, David Waite wr

Indeed both are reasonable but perhaps suboptimal. Consider the following potential changes. // Assume this code is included for the below examples. func myThrowingFunc() throws -> String { if drand48() < 0.5 { throw NSError(domain: "", code: 0, userInfo: nil) } return "" } l

Re: [swift-evolution] use standard syntax instead of "do" and "repeat"

In a block of code where errors are only thrown in some places, do+try is illustrative because it allows you to know which functions are possible failure points. However, in a block of code where errors are thrown in most places, a try block would be useful because individual try statements bec

Re: [swift-evolution] use standard syntax instead of "do" and "repeat"

I think we want to leave throws and rethrows at the method signature level and to mean that we want to throw an actual exception so I would not reuse it this way as it would be confusing. Sent from my iPhone > On 29 Dec 2015, at 14:24, Amir Michail wrote: > > >> On Dec 28, 2015, at 6:12 PM,

One could say that is extremely petty to redefine very commonly accepted words (private when we mean file restricted, internal when we mean essentially package when there are already pretty well understood meaning from languages which quite frankly Swift will not kill now or 5 years from now...

[swift-evolution] use standard syntax instead of "do" and "repeat"

So “try” instead of “do”. If there is no catch, then just use braces without a keyword for a block. And use do-while instead of repeat-while. ___ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evo
