Content
Other methods validate explicitly their arguments with _validate_value_types for example. Here it raises KeyError which does not seem to be the appropriate exception. ConfigParser implementing the mapping protocol it seems weird to me to have >>> a = 123 >>> config[a] = {} >>> config[a] KeyError: 123 I would have prefered a TypeError to be raised on __setitem__ but this is now documented behavior.
