No that returns the subarray starting from index 5 to the end.

What I want to be able to return

array([0, 1, 2, 3, 4, 5])

(i.e. last element 5 included)

but without the funky A[0:6] syntax, which looks like it should return

array([0, 1, 2, 3, 4, 5, 6])

but since bumpy arrays omit the last index, returns

array([0, 1, 2, 3, 4, 5])

which syntactically would be more reasonable to be A[0:5].
