    This could be written as:
    
    res.extend([inc.get_sections(key, attr, searched) for inc in self._includes])
    
    Two reasons for this change:
    (1) generally, list comprehensions are a bit faster than for loops that build a list.
    (2) using an explicit extend with a list comprehension informs the reader of the intent of the code over the += operator. (Note: the difference between '+' and '+=' on a list caught me by surprise the first time. I'm less a fan of using operators on a list than using explicit methods.)
