```

### Use Cases

```py
from ast_selector import AstSelector

tree = load_python_code_as_ast_tree()
query = "FunctionDef.returns[id=int] $FunctionDef"

function_element = AstSelector(query, tree).first()
```

It's extremely hard to keep hacking on open source like that while keeping a full-time job. I thank God from the bottom of my heart for both the inspiration and the energy.
