[Numpy-discussion] Python 3 dict support (issue #5718)

[Hannah]

Hi,
I started venturing down the rabbit hole of trying to write a patch to add
support for numpy to convert python 3 dictionary keys
(collections.abc.ViewMapping objects), which is open issue #5718 and am
having trouble orienting myself. I'm unclear as to where the python entry
point into array is (basically, what function np.array drops into and if
this is in Python or C) and where/what language (fine with writing either)
a patch that supports MappingViews would go. Any help getting oriented
would be much appreciated.

The reasoning for the patch is s that dicts are one of the most common
Python datatypes and this specifically is because of an upstream issue of
wanting dict support in matplotlib.

Thanks,
Hannah
