or let(::loveThePet)

Thanks @Matheus i`ll probably stick to the first approach you suggested .let{ method(it) }

I think that's the best approacah in Kotlin, as you can do stuff like

getHuman()
.let { marryTo(it, human2) }

it wouldn't be possible to translate this from Elixir, which is a bit more idiomatic imo

getHuman()
|> marryTo(human2)

Unless you use some sort of currying library that curries functions backwards somehow? lol
