We pass down the correct default annotation indicator to use in 100% of code rendering places, so this becomes a useless bit of initialization. We already set this to a sentinel by default, and the only thing that having an explicit str gives us is the inability to copy an annotation from a param to a return or vice versa. So, out it goes. This means we can't render Annotation by itself, so the test that was using this behavior is out too.
This finishes the parser! 🎉
A few related changes were made:
- `DummyNode` was removed, as it's no longer needed.
- `lpar`/`rpar` was removed from `StarredDictElement`, because I found
out that it's not valid syntax while developing the parsing logic.
