Hi, can I create an extension static method to all classes ? I tried this

inline fun <T : Any> T.create(block: T.() -> Unit) = jso(block)

But the receiver type is of the companion object of the class and doesn't work if the class doesn't have any companion object, so this is not what I want

I want to be able to do AnyClass.create { } and have the receiver equal to the receiver when doing AnyClass().apply { }

No, it's not possible.

If https://youtrack.jetbrains.com/issue/KT-11968 is implemented, it would be possible to provide a static extension for an arbitrary, but still a concrete type. However, we're also exploring the design space of the further possibilities, such as providing "static-like" extensions for a generic type.

Okay, I voted for it ^^

You can do inline fun <T : Any> KClass<T>.create(block: KClass<T>.() -> Unit) = jso(block)
and AnyClass::class.create {}

you could implement it using reflection
