FYI ten alignment je udělaný špatně. http://www.python.org/dev/peps/pep-0008/#indentation
```python
                self.compose_greedy_lookahead = int(re.search(r'\d+', 
                                                              compose_setting).group(0)) 
```
To už je docela dlouhé, takže by šlo
```python
                self.compose_greedy_lookahead = int(
                    re.search(r'\d+', compose_setting).group(0)) 
```
