Or maybe source code :slightly_smiling_face: <https://github.com/JetBrains/kotlin/blob/1ab003c029c4476319754df931536cffd518b004/core/descriptors/src/org/jetbrains/kotlin/util/modifierChecks.kt#L177>

dkandalov: Thanks. The source indeed seems to be the most complete list. It would nice if the docs had a concise and complete list, though.

Looking at the source, I wonder what the next and hasNext operators are. They sound like Iterator's methods, but I don't know why they need the operator modifier.
