I just noticed the source link for Unit is broken on the kotlinlang website.  Wasn't sure the best place to report...
<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html>
Click on the Unit source link.  It looks like the latest version isn't there, because if you change the url from 
<https://github.com/JetBrains/kotlin/blob/1.2.51/core/builtins/src/kotlin/Unit.kt#L22>
to (1.2.50) its there
<https://github.com/JetBrains/kotlin/blob/1.2.50/core/builtins/src/kotlin/Unit.kt#L22>
