You are turning keyword arguments into positional arguments. The order of
entries in a dict is undefined and may even vary between runs of python:
$ PYTHONHASHSEED=random python -c 'print dict(foo=1, bar=2, baz=3).items()'
[('baz', 3), ('foo', 1), ('bar', 2)]
$ PYTHONHASHSEED=random python -c 'print dict(foo=1, bar=2, baz=3).items()'
[('baz', 3), ('foo', 1), ('bar', 2)]
$ PYTHONHASHSEED=random python -c 'print dict(foo=1, bar=2, baz=3).items()'
[('baz', 3), ('bar', 2), ('foo', 1)]
$ PYTHONHASHSEED=random python -c 'print dict(foo=1, bar=2, baz=3).items()'
[('foo', 1), ('baz', 3), ('bar', 2)]
If you want to turn keyword arguments into positional arguments you have to
think about a mechanism to ensure the intended order.
