Is there is specific reason that < etc are not supported in when
(I mean in the same way as in and is)

You can use ranges

[Luca Nicoletti]

eg: when(position) { in 0..3 -> {} }

[Matteo Mirk]

I don’t know in details, probably they’re not supported because of how Kotlin grammar is defined: https://kotlinlang.org/docs/reference/grammar.html#whenCondition
In the end you can always use them more verbosely:

val i = 42
when {
    i < 10 -> println("low")
    i >= 10 -> println("hi")
}
