Hi there,

When I run -version on compiler, it goes into an interactive shell (shouldn’t -version prints info and exit?) Also I think printing JDK version would be helpful.

Anyway, I try the interactive shell, but a simple line like below crash the shell.

```kotlin
bash> bin/kotlinc-jvm
Kotlin interactive shell
Type :help for help, :quit for quit
>>> fun test(){ println("hello") }
>>> test()
hello
>>> class Foo{}

```

So I guess the shell is not quiet ready yet?

Interactive shell have status of a prototype, and we are not developing it right now.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Then please fix -version option so users wont' encounter this.
