Is it possible to embed the file path and line number at compile-time? Something like __FILE__ and __LINE__ in C. The goal is to have a function that measures the performance of some code, and is able to report it with a link to its call, for ease of debugging.

I know it's possible to get that information by throwing an exception, catching it and exploring the stacktrace, but that would have a performance impact, whereas this should be able to be embedded at compile-time to avoid any performance difference.

.main.kts already supports __FILE__, although it's handled as a val that the script runner supplies at runtime

but what you're asking for is really https://youtrack.jetbrains.com/issue/KT-34553/Provide-source-location-information-through-compiler-intrinsics right?
