Kotlin 1.1-M02 （Early Access Preview）发布了，这是 Kotlin 1.1 的第二个里程碑版本，也带来了大量更新。这个版本带来了让人期待已久的新语言特性，在 lambdas 表达式中的解构，同时还有许多基于 1.1-M1 的新特性改进。部分更新如下：

语言特性

• 用于 lambdas 表达式的解构 (proposal)

  Current limitations:

  • Nested destructuring is not supported

  • Destructuring in named functions/constructors is not supported

  • Is not supported for JS target
