[Numpy-discussion] just how 'discontiguous' can a numpy array become?

Yes to Q1 and No to Q2.

Discontiguous arrays are very easy to create: for example, if you say
np.empty((10, 50), order="F"), you have a discontiguous array. I use
this quite often when I need to interoperate with C or Fortran
libraries - interoperation with other libraries/formats is another
common source of discontiguous arrays, compared to memory views.
