I’ll throw my syntax suggestion into the mix: backslashed brackets for the braces, a colon for the separator.
let fsa: \[3: Int\] = \[3: 1, 2, 3\] Or maybe go the string interpolation route and only backslash the first bracket. let fsa: \[3: Int] = \[3: 1, 2, 3] I think that looks pretty clean. For one-dimensional arrays, you could even omit the size and infer the type. let fsa = \[1, 2, 3] // Of type \[3: Int] And I agree with Taylor that the separator chosen should have no standalone use in the language — colon, semicolon, pound sign, etc are OK, but operators shouldn’t be used. > On Jul 23, 2017, at 12:08 PM, Taylor Swift via swift-evolution > <swift-evolution@swift.org> wrote: > > Using the multiplication operator as a separator character seems like an > extraordinarily bad idea. > > let fsa:[2 * Int] = [2 * 5, 3] // [10, 3] ??? > > On Sun, Jul 23, 2017 at 11:59 AM, David Sweeris <daveswee...@mac.com > <mailto:daveswee...@mac.com>> wrote: > > > Sent from my iPhone > > On Jul 23, 2017, at 08:45, Taylor Swift via swift-evolution > <swift-evolution@swift.org <mailto:swift-evolution@swift.org>> wrote: > >> >> >> On Sun, Jul 23, 2017 at 5:29 AM, Adrian Zubarev via swift-evolution >> <swift-evolution@swift.org <mailto:swift-evolution@swift.org>> wrote: >> I wanted to read the proposal, but skipped it as soon as I’ve seen the >> syntax.
