我希望看到fun let的源代码，但是在我按下ctrl键之后，我得到了以下内容.
如何在Android Studio 3.1.3中查看Kotlin的乐趣源代码？
@kotlin.internal.InlineOnly public inline fun <T, R> T.let(block: (T) -> R): R { /* compiled code */ }

现在，当系统今天更新Kotlin插件时就可以了.
I think that the system update the plugin failed caused the problem.
如何手动更新插件？您知道，系统并不总是显示更新插件UI！

我可以在kotlin-stdlib-common-1.2.51.jar中看到let的源代码，路径是kotlin -> Standard.kt (or file name showing as StandardKt.kotlin_metadata).我也在执行同样的命令.
Below is code of that fun
/**
* Calls the specified function [block] with `this` value as its argument and returns its result.
*/
@kotlin.internal.InlineOnly
public inline fun <T, R> T.let(block: (T) -> R): R {
contract {
callsInPlace(block, InvocationKind.EXACTLY_ONCE)
}
return block(this)
}
