Reactor Kotlin Extensions 1.0.0.M1 released

Update: Kotlin is now natively supported by reactor-core and reactor-test without requiring any additional extensions.

I am excited to announce the release of the first milestone of Reactor Kotlin Extensions, which provides Kotlin extensions for Reactor API.

It provides support for Kotlin types like KClass, takes advantage of Kotlin reified type parameters and provide various extensions to allow more expressive code. You can see bellow a quick comparaison of Reactor with Java versus Reactor with Kotlin + extensions.

Java Kotlin with extensions
Mono.just("foo") "foo".toMono()
Flux.fromIterable(list) list.toFlux()
Mono.error(new RuntimeException()) RuntimeException().toMono()
Flux.error(new RuntimeException()) RuntimeException().toFlux()
flux.ofType(Foo.class) flux.ofType<Foo>() or flux.ofType(Foo::class)
StepVerifier.create(flux).verifyComplete() flux.test().verifyComplete()

To use it in your project, add https://repo.spring.io/milestone repository and io.projectreactor:reactor-kotlin-extensions:1.0.0.M1 dependency.

This is the very first milestone, so feel free to create issues and submit pull requests on reactor-kotlin-extensions GitHub project.
