Stupid question. How to make external class extend non-external?

external class MyError extends Error { ... }

Hi Ivan,
First of all, to make it clear, external modifier is applicable only to interfaces.
And answering to your question, no, we cannot inherit external interface from non-external

im using ts2kt to convert typescript typings.

I apologize for confusion. Sure it is possible to create external class in Kotlin/JS but inherit it from non-external class is prohibited.

Is that due to ES 6 not being supported in Kotlin JS?
