Is it possible to tell Kotlin compiler to generate inner static classes out of object expressions?

[diesieben07]

Does it not do that? It does for me, also setting the enclosing class and enclosing method tags properly.

[dstarcev]

They are local which leads to an issue with jackson deserialization https://github.com/FasterXML/jackson-module-kotlin/issues/135

[diesieben07]

There is no object expression in the code posted there. There is a local class, hence Class#isLocalClass returns true. This is not Kotlin's "fault", the same would happen in Java.

[dstarcev]

when I do something like

fun foo(bar: Sting): Any {
  val obj = object : SomeClass() {
    val buz = bar
  }
  return obj;
}

[dstarcev]

it becomes local too

[diesieben07]

Yes. Local means "inside a method".

[dstarcev]

So, I want the compiler to make it non-local

[spand]

why not just move it out of the fun ?

[diesieben07]

But it is local... You want the compiler to generate wrong metadata...

[dstarcev]

Because this is less verbose when the object is defined in the method. And I don't have to invent a name for the class

At the same time, I need it to be json (de)serializable
