[Numpy-discussion] Approving NEP 27 - Historical discussion of 0-D arrays

[Matti Picus]

In PR 12166 https://github.com/numpy/numpy/pull/12166 we revived an old 
wiki document discussing the implementation of 0-dimensional arrays. 
This became informational NEP-27 
http://www.numpy.org/neps/nep-0027-zero-rank-arrarys.html. There was 
fruitful discussion of the NEP and the need for both 0-D arrays and 
scalars on the PR comments. The NEP itself is informational and freezes 
the information to the 2006 discussion, noting that "some of the 
information here is dated, for instance indexing of 0-D arrays now is 
now implemented and does not error."


I would like to submit the NEP for discussion and approval.
