Option<Unit> seems like a better option than Either

[Tiberiu Tofan]

I guess you can create your own extension function, though I don’t really see a use case for it, I find if expressions good enough. Something like:

fun <R> Boolean.fold(ff: () -> R, ft: () -> R): R = if (this) ft() else ff()

Simon shared conditionally(), which does the perfect job. Thank you for providing an option, Tiberiu 🙌
