A very nice shortcut in my opinion is the one supported by the HP
scientific calculators (HP28, HP48 in my days), which would look like:

array([[0,1,0], 1, 0, 0, 0, 0, 1])

I'm not quite sure how this could be generalized nicely for arbitrary
shapes, but for arrays of rank 2 (which are a very common case where
people are actually typing the values) it feels nice (especially on a
french keyboard where the square brackets are awkward to type in)
