Btw: The name "read_dict" [1] as well as its docstring say exactly the opposite
of what it does. It acts as a "save_dict". Maybe that can be fixed on the go ...
The docstring
""" [...]
All types held in the dictionary are converted to strings during
reading, including section names, option names and keys. [...]
"""
actually implies what is my proposal here: Convert arguments to str during
lookup as well.
```
def __getitem__(self, key):
if key != self.default_section and not self.has_section(key):
raise KeyError(key)
return self._proxies[key]
```
to
```
def __getitem__(self, key):
try: key = str(key)
except (WhateverError, IsRelevantHereError): raise KeyError(key)
if key != self.default_section and not self.has_section(key):
raise KeyError(key)
return self._proxies[key]
