When calling a generic method from IR, i.e. "to", if the return type isn't explicitly specified as part of "irCall" the linker will fail with very unintuitive errors. Sample project is attached. To setup, comment out the "id("com.rnett.error-gradle-plugin") version "1.0-SNAPSHOT"" use in "test/build.gradle.kts", run "error-compiler-plugin:publishToMavenLocal" and "error-gradle-plugin:publishToMavenLocal", and un-comment the plugin use. Multiple test functions are in "test/src/jsMain/kotlin/com/rnett/error/Test.kt", with what the compiler plugin tries to set their bodies to in comments. Uncomment the ones you want to try and run "Test Compiler Js" or "Debug Compiler Js" run configurations. "test4" and "test5" showcase this the best: they both add "Helpers.otherTest("1" to "2")", but test 5 passes the return type as part of "irCall" and works, while test 4 fails. The relevant compiler plugin code is in "error-compiler-plugin/src/main/kotlin/com/rnett/error/compiler/ErrorMethodTransformer.kt".…
