Out of curiosity, is there an idiomatic way of filtering lists by adjacent distinction?

e.g.

listOf("a", "b", "b", "a", "b").distinctFromAdjacent()
// result a,b,a,b

[Ruckus]

maybe

listOf("a", "b", "b", "a", "b")
    .windowed(2, partialWindows = true)
    .filter { it.size == 1 || it[0] != it[1] }
    .map { it[0] }

I did not know about windowed thanks!
