I've found myself implementing this in a couple of different projects now... do you guys think there might be a place for it in the standard library?

The closest I've got using the existing functions is chaining filterIsInstance and first but I imagine this is a little better performance wise as we are returning after the first match.

It's like first is to filter... `firstIsInstance`/`filterIsInstance` 😄

inline fun <reified T> Iterable<*>.firstIsInstance(): T? {
    for (element in this) {
        if (element is T) {
            return element
        }
    }

    return null
}

I'd really like this too. Maybe even a contract that allows it.

I'd rename that to have orNull on the end to match the standard library. Maybe firstInstanceOfOrNull<T>()?

I think that makes sense 👍

if you do filterIsInstance and first on a sequence, that would also return on the first match, wouldnt it?
