Quite a lot of work, we need to list/detect common situation where we could find an identation in a CommaList and see how we have to behave. Here is an example of a failing situation. A "quick win" would be to have a default behavior (even a bad one) instead of an exception (which sucks). ``` python In [7]: RedBaron("def __init__(self, a,\n b, c): pass")[0].arguments.pop() --------------------------------------------------------------------------- Exception Traceback (most recent call last) <ipython-input-7-4d3f9b02d5b0> in <module>() ----> 1 RedBaron("def __init__(self, a,\n b, c): pass")[0].arguments.pop() /home/psycojoker/code/python/redbaron/redbaron/base_nodes.pyc in pop(self, index) 1348 else: 1349 self.data.pop() -> 1350 self._synchronise() 1351 1352 def remove(self, value): /home/psycojoker/code/python/redbaron/redbaron/base_nodes.pyc in _synchronise(self) 1325 1326 def _synchronise(self): -> 1327 self.node_list.data = self._generate_expected_list()[:] 1328 self.data = self._build_inner_list(self.node_list.data) 1329 /home/psycojoker/code/python/redbaron/redbaron/base_nodes.pyc in _generate_expected_list(self) 1493 if self.style == "indented": 1494 if not expected_list[-1].second_formatting.endl: -> 1495 raise Exception("Unhandled case") 1496 elif expected_list[-1].second_formatting.endl.indent != self.parent.indentation + " "*4: 1497 expected_list[-1].second_formatting.endl.indent = self.parent.indentation + " "*4 Exception: Unhandled case ```
