TBH, I wouldn't have expected it to work, but now that I see it, it does make some sense. I would have thought that it would error out as being ambiguous (prepend? append?). I have always used ellipses to make it explicit where the new axis should go. But, thinking in terms of how regular indexing works, I guess it isn't all that ambiguous.

Yeah, I'm not really a fan of the rule that indexing with too-few axes implicitly adds a "..." on the right A[0] -> A[0, ...] but given that we do have that rule, then A[None] -> A[None, ...] does make sense. -n -- Nathaniel J. Smith -- http://vorpus.org
