```python

...     print 'A:', args
...     print 'KW:', kwargs
...                                                                                                                                                                                                                                            
>>> foo('bar', **dict(extra=True))                                                                                                                                                                               
A: ('bar',)                                                                                                                                                                                                                                    
KW: {'extra': True}

```
So, in fact, the call can simply be `_salt('lxc.list', extra=True)`... No?

```python
>>> foo('bar', extra=True)
A: ('bar',)                                                                                                                                                                                                                                    
KW: {'extra': True}                                                                                                                                                                                                                            
>>> 
```
Or am I missing something?
