I have a question about Kotlin 1.3 coroutines. When I took on one of suspend function that return String by ByteCode Viewer, I noticed <undefined type>

#coroutines (also, you never asked a question)

Oh, How I get

if (var1 instanceof <undefinedtype>) {
            $continuation = (<undefinedtype>)var1;

i guess the bytecode viewer / decompiler to java might not be perfectly handling the continuations ?

I could upload that function from bytecode viewers into gist

my best guess still is that there is bytecode magic and the decompiler (ferflower iirc( cannot turn it into java
