Proposal:

It was discussed in the context of adding controversial AttrDict. The reason for adding AttrDict was to allow JSON object attributes to be accessed as Python object attributes rather than dict keys. The reason for not using SimpleNamespace for this was that you need to use a wrapperlambda x: SimpleNamespace(**x), which makes this solution less obvious.

Supporting a positional argument inSimpleNamespace(), which can be a mapping or an iterable of key-value pairs (like in thedict constructor) will make using SimpleNamespace with JSON more convenient.

SimpleNamespace({'a': 1, 'b': 2}) is the same asSimpleNamespace([('a', 1), ('b', 2)]) is the same asSimpleNamespace(a=1, b=2).
