May 2017 commit https://github.com/JetBrains/kotlin/commit/00a5ff23643d2b753ba2140d2baa72f05480cf06 fixes a typo in language grammar, but the typo is still in the docs. Somebody probably forgot to regenerate documentation https://kotlinlang.org/docs/reference/grammar.html

It's possible, because I know some of the samples that were added recently aren't there yet either.

@stanislav.erokhin ^^

Any updates on this?
