Can you give some example use cases of where this would help? "throw" already takes a string argument, so the error message can be as helpful as you want it to be. If the "throw" error message cannot show a helpful message because it lacks context (e.g. deep in some function call), the necessary context could be passed in as a string argument, for instance. -- Eelco Dolstra | http://www.st.ewi.tudelft.nl/~dolstra/ _______________________________________________ nix-dev mailing list [email protected] https://mail.cs.uu.nl/mailman/listinfo/nix-dev
