[swift-evolution] Range and ClosedRange

[Adriano Ferreira]

Hi David,

There were a few instances where this topic or similar came up at the Swift Evolution List <https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160905/026923.html> and Swift Users List <https://lists.swift.org/pipermail/swift-users/Week-of-Mon-20161010/003631.html>.

There’s even this interesting proposal <https://github.com/luish/swift-evolution/blob/f99e325484a5b19ce4bab8eda18f284e4e250e7b/proposals/nnnn-more-lenient-collections-subscripts.md> that dwells with it while providing more lenient subscripts to collections.

BTW, I agree with you, having the range type split is somewhat confusing, specially for those new to the language.

Best,

—A

I’ve seen people confused when writing an API that takes a Range as argument but then can’t pass in a ClosedRange. Sometimes this can be fixed because the API should be written against a more general protocol, but sometimes that’s not the case.
