Does Kotlin have a "character"?

Question

I continue to find the trait mentioned in the Kotlin examples. For example, this answer uses trait .

Is the trait keyword used in Kotlin? If so, where can I find information about it, and if it is not, was this part of the language specification at some point?

Answer 1

The trait keyword was a keyword in Kotlin, but now it has been removed. This was deprecated on the release of the Kotlin M12.

Here you can find.
