when I dont' use the result of the builtin `copy()` function of data classes Intellij highlights the code as a warning (with error of "Unused result of data class copy").

is there a way to get warning activated for my own functions, when I don't use the result value?

Although note that there are Android only (<https://developer.android.com/reference/kotlin/androidx/annotation/CheckResult>) and Compose (<https://developer.android.com/reference/kotlin/androidx/compose/runtime/CheckResult>) versions of that annotation already if you're working on those specific platforms/feature sets

thanks for the info, will be watching the issue...

How about a `pure` keyword (or `@Pure` if it has to be an annotation)? Less verbose, and by definition there’s no point calling a pure function unless you use the result. 

you may want to enforce users to look at the result even if it's not pure
