The Scala snippet works for all inputs, it's something you would see on a real codebase. It also scopes the regex captures within the match expression. The code also scales better for more complex cases where a string is tested against multiple regexes, or against specific captured values. I assume this Kotlin snippet would, at minimum, need to do null-checking on "matchEntire" before it finds its way to a production codebase.
