↓なんかうまくいかない。何かミスってる？？ infix operator => : SwifletPrecedence precedencegroup SwifletPrecedence { higherThan: AssignmentPrecedence associativity: left } func =><T>(lhs: T, rhs: (inout T) throws -> ()) rethrows -> T { var value = lhs try rhs(&value) return value } print([Int]() => { (a: [Int]) -> () in a.append(42) })
$ swift inout-let.swift inout-let.swift:14:40: error: value of type 'Any' has no member 'append' print([Int]() => { (a: [Int]) -> () in a.append(42) }) ^ ~~~~~~ inout-let.swift:14:40: note: cast 'Any' to 'AnyObject' or use 'as!' to force downcast to a more specific type to access members print([Int]() => { (a: [Int]) -> () in a.append(42) }) ^ ( as AnyObject) (edited)
