Code after return

No wonder it was wrong -- this paragraph-to-code relationship is quite demanding to follow.

btw, I'm not used to reading templates, but are these lines after the `return True` even reachable?
```python
return True # success{% for field in messages["set"][msg].payload %}
m.{{field.name}} = {{field.name}}
{% endfor %}
m.pack_msg_data()
self.write(m.msg_data)
```
