indexing using pycall get differs from python

I have read this:

Given o::PyObject, get(o, key) is equivalent to o[key] in Python, with automatic type conversion. To get as a PyObject without type conversion, do get(o, PyObject, key), or more generally get(o, SomeType, key). You can also supply a default value to use if the key is not found by get(o, key, default) or get(o, SomeType, key, default)

With this I successfully sliced a Python object ndarray in the first direction using:
image = get(image, PyObject, 5:70)
The problem is that I want to be able to do (in python) img[5:70, 5:200], use multiple arguments in brackets, but when typing
image = get(image, PyObject, 5:70, 5:200)
the second argument in seen as the default argument. So wouldn't it be nice to be able to give multiple arguments using get?

image = get(image, PyObject, (5:70, 5:200)) results in

まず、issueで説明されているPyCall get APIを追跡し、Python ndarrayに対する多次元インデックス指定を再現します。個別のslice引数とtuple形式を比較し、デフォルト引数が現在どのように区別されているかを明らかにします。完了条件は、要求どおり多次元インデックス指定が機能すること、または回帰テストによってサポートされる動作が明確になることです。
