Is there any way to force some code to be run non-lazily when the JS file is loaded? Even when using -Xir-property-lazy-initialization.

With -Xir-per-module I need to know if a certain module was already loaded. The only which comes to mind is to set a global variable when loading that module, and check if that variable set from other modules.

Currently there are two custom things that run during module load with `-Xir-property-lazy-initialization`:
• top-level main function
• tests annotated with kotlin.test.Test
Either should work

import kotlin.test.Test

class Foo {
    @Test
    fun foo() {
        thisModuleIsLoaded = true
    }
}

// At most one main function per module
fun main() {
    thisModuleIsLoaded = true
}

@Svyatoslav Kuzmich [JB] unfortunately it doesn’t work with “top-level main function” when also using -Xir-per-module.

The main functions of modules get dead-code-eliminated.

I can force-keep it with with @JsExport but then I run into another issue because multiple modules export a symbol with the same name `main`:

IllegalStateException: IrSimpleFunctionPublicSymbolImpl for public /main|-4284757841571462650[0] is already bound: FUN name:main visibility:public modality:FINAL <> () returnType:<Uninitialized>

Any other ideas how to run code when such a module loads?

Oh I found a workaround. These main funs need to be private 😮

@JsExport private fun main()
