i dont trust any piece of software that has all these made-up, unrelated, non-reflecting names. I mean come on, arrow, maya ? the main challenge about software engineering is correct naming. If you fail there you pretty much fail in the rest. Same goes for actually builtin name, "datetime". There is no such thing in real life as datetime. There is date and there is time. They are very separate notions and the root of the problem IMO is in trying to pile them together.
