kotlinlang

I'm running into an issue with Android Studio 2.2.3 and Kotlin 1.1.0-beta-22. In the build.gradle for my project I've defined the property `ext.kotlin_version = '1.1.0-beta-22'`, added the maven repository (`maven { url '<http://dl.bintray.com/kotlin/kotlin-eap-1.1>' }`) and set the classpath (`classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"`). In the kotlin-stdlib is also in the dependencies for my app module and refers to the same property (`compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"`) and the kotlin-android plugin is applied at the top (`apply plugin: 'kotlin-android'`). But somehow I'm still getting the following error when I try to use a method reference: `This feature is only available since Kotlin 1.1: bound callable reference`.
