and that in keyword can be used in a when for any operator fun contains, whether it's defined as String.contains, List.contains, your own custom type's contains function, etc

Would an example be:

when (charInput) {
  in "Adam" -> println("Yay")
  else -> println("Nope")
}

[kevinmost]

well charInput in "Adam" is equivalent to saying "Adam".contains(charInput) (in all instances, not just in a when, this is a standard Kotlin operator), so for example, "A" would hit your "Yay" block in this case, but "Adam McNeilly" would hit your "Nope" block

[kevinmost]

but that when block is valid syntax, yes

Right, I was just tyring to equate `charInput in "MyString" with contains which I didn't know was true. This is neat.
