A modern programming language that makes developers happier.

I've noticed that companion objects behave in a lazy-fashion of sorts. For example, having
```open class B() {
    init {
        println("Instance of B created!")
    }
}

class A {
    companion object Companion: B()
}```
B's `init` won't be called unless I access `A` in any way, or create an instance of it (`A.Companion`, `A()`). So this isn't *just* like Java's `static` (as the docs point out anyway: "Note that, even though the members of companion objects look like static members in other languages, *at runtime those are still instance members of real objects, and can, for example, implement interfaces*"). But this lazy-thing is something I wasn't expecting. Can I expect this behaviour no matter the platform?

a. expected due to how JVM works, class initializers only run as needed
b. no, <https://youtrack.jetbrains.com/issue/KT-40768>
