I do not see sufficiently measurable benefits to this proposal to add it to the language. It's easy enough to roll your own `repeatForever` function with trailing closure.
I also want to thank you for bring it up on-list. Not every idea is right for Swift but it's always refreshing to see innovative thoughts added to the discussion. Please do not be discouraged by the generally negative feedback on this particular idea. -- Erica > On May 10, 2016, at 1:27 AM, Nicholas Maccharoli via swift-evolution > <[email protected]> wrote: > > Swift Evolution Community, > > Currently writing an infinite loop in swift looks either something like this: > > while true { > if ... { break } > //... > } > > Or this: > > repeat { > if ... { break } > //... > } while true > > But I think it might be best to change the syntax / behaviour of `repeat` to > loop > indefinitely if no trailing while clause is present: > > repeat { > if ... { break } > //... > } > > while still allowing a trailing `while` clause as in: > > repeat { > foo += bar > } while foo.count < limit > > I also want to propose that it should be a compile time error to use single > `Bool` constants as while loop conditions, so no more `while true { ... }` it > would become `repeat { ... }` > > I was thinking of drafting a short proposal if there was enough positive > feedback. > > How does it sound? > > - Nick > _______________________________________________ > swift-evolution mailing list > [email protected] > https://lists.swift.org/mailman/listinfo/swift-evolution
