nix-repl> builtins.throw "what"
error: what


Starting REPL to allow you to inspect the current state of the evaluator.

nix-repl>

nix-repl> builtins.throw "what"
error:
       … while calling the 'throw' builtin
         at «string»:1:1:
            1| builtins.throw "what"
             | ^

       error: what
