I was going through the course and ran into this failing test case which uses assignment in Lox. This stage handles only redeclarations while assignments are not handled until the next stage.

```auto
var quz = 2;
print quz;
quz = 3;
print quz;
var world = 5;
print world;
quz = world;
print quz;

```

Thanks! 😁

Thanks for highlighting this!

Our team will fix the test cases by tomorrow, and I’ll update you as soon as it’s done.

We’ve just updated both the [stage instructions](https://github.com/codecrafters-io/build-your-own-interpreter/pull/44) and [the tester](https://github.com/codecrafters-io/interpreter-tester/pull/40), properly (re)declaring variables using the `var` keyword.
