Found a nice usage of generateSequence for second part of Day 15:

return generateSequence(4) { it + 1 }
    .map { elfAttack -> fight(inputs, elfAttack) }
    .first { result -> result.beings.none { it.kind == BeingKind.ELF && !it.alive } }
    .score

The solution becomes a lot faster if you cancel a battle right away with the first elf death, instead of letting them all finish and looking afterwards.

Makes sense 👍
