We need a better place to collect and track all valuable discussions around Kotlin. But I'm afraid this forum can't support it well currently.
Its content is not friendly to search engines. I got no result while google with “site:devnet.jetbrains.com kotlin resourceholder”
The built-in forum search returns empty result with keyword “resourceholder” too
While the post I’m searching for does exist: https://devnet.jetbrains.com/thread/465938?tstart=30
