Another small nitpick: The test suite currently generates 270 warnings. Would be good to review if there's anything critical in there

@ajitjohnson This is looking very promising! With the addition of your tests of whole arrays, consider my wish for integration testing covered as well. As mentioned, I mostly wanted to...
