I am learning kotlin, and just implemented some simple stream processing code with a SAM style transform interface:

interface ByteArrayTransformer {
    fun transform(input: ByteArray): ByteArray
}

Doing so enabled things like wrapping transformers with timers, logging, etc. by extension functions.

Does Kotlin have the means to declare a typed function signature, so that I could drop the reliance on classes, and fully open the door to closures, without having to declare the same func signature all over the place?
