It seems like `__multicall__.execute` is the first thing to do in either case for this conditional, so I wonder if you can save yourself some whitespace below here with a short circuit, similar to the `if register_event.listener is None` check:

```python
__multicall__.execute()

if 'register_event' not in item.funcargs:
    return

register_event = item.funcargs['register_event']

if register_event.listener is None:
    return

...
```
