Need another good example of using builtins.trace

I have seen it described, but have had no luck using Builtins.trace.

Is there a trick? Is there a piece of nix code (not a build expression) which I can import from nix repl and see how to do it?

There are some extractions available in lib.debug, you can also study their source to learn about how to use builtins.trace


Yup. Pretty helpful. Thank you
