title: Does the jar library built from Kotlin code still have all the feature like accessing local Kotlin code
body: <p>I am looking at this <a href="https://docs.gradle.org/current/samples/sample_building_kotlin_libraries.html" rel="nofollow noreferrer">https://docs.gradle.org/current/samples/sample_building_kotlin_libraries.html</a></p>
  <p>to build a Kotlin jar library. But I am wondering -- if consumer code of the library is also using Kotlin, can it have all the benefits like accessing to local Kotlin code? For example:</p>
  <ol>
  <li>Nullability check</li>
  <li>Suspend keyword restriction</li>
  <li>Named parameters</li>
  <li>...</li>
  </ol>
