Double-clicking the variable's value in the side panel produces a text input for users to modify. Changing it from `hello world` to `another string` was producing an error, effectively because it was evaluating `str = another string`.

Now the user can modify it to `another string` and it accepts it with implicit quotes as `"another string"`.

When setting it to a non-string like `42`, the variable does become a number type. If. user types in `"42"` in the text input, it's appropriately a string.
