Hello, I found an annoying behaviour here (https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/first.html), if the array is empty it is thrown a NoSuchElementException. I found that I can obtain what I want using filter and then checking against list size. I was expecting to return a `T?`(meaning an optional of some kind) instead of T. So basically instead of doing list.first({p -> predicate}).orElse(defaultObject) I have to do something like var result = list.filter({p -> predicate}); if(result.isEmpty()) return defaultObject else result.first(). Do you think there is a better approach?

Use firstOrNull() instead of first()

[spand]

ie. list.firstOrNull { pred(it) } ?: defaultObject
