I'm kinda-sorta still getting around to building/reading the sphinx
docs for datarray. <_< Like, I've gone through them before, but it was
more cursory than I'd like. Honestly, I kinda let myself get caught up
in trying to automate the process of getting them onto github pages.
I have to admit that I didn't 100% understand the reasoning behind not
allowing integer ticks (I blame jet lag--it's a nice scapegoat). I
believe it originally had to do with what you meant if you typed, say,
A[3:"london"]; Did you mean the underlying ndarray index 3, or the
outer level "tick" 3? I think if you didn't allow integers, then you
could simply wrap your "3" in a string: A["3":"London"] so it's
probably not a deal-breaker, but I would imagine that using (a)
separate method(s) for label-based indexing may make allowing
integer-datatyped labels.
Thoughts?
