Hello!
I’m not sure where to go with this question, so please let me know if there’s some kind of documentation or example which I can take a look at.
I’m currently trying to add support for kotlinx.collections.immutable to kotlin-parcelize plugin.
At the moment I’m trying to figure out how can I correctly build symbol for the kotlinx.collections.immutable.toPersistentList extension function and call it on IrVariable as a receiver.
Originally ``kotlinx.collections.immutable.toPersistentList`` is defined in extensions.kt file.
So, I assume that I need to build symbol for the ExtensionsKt.toPersistentList(iterable: Iterable<T>) static function?
Is it correct or I should go in another direction?

If you are working at IR level in plugin, you should think about declarations from kotlin point of view, not from any platform
So you need to look up for functions with CallableId package = kotlinx.collections.immutable, name = toPersistentList and then choose one which suites you by types of parameters/receiver/return type
