I think there are two salient questions:
- Where this lives in the API: Should this be under `construct`? I don't think the kwarg should be called `fill_value` - that traditionally has a specific meaning of ""the value to replace `NaN` with"". I don't understand the `periodic` reference, but likely I'm missing something. Could be `wrap=True`, or `roll=True`?
- How it's implemented - do you have a view here? Can you use the `construct` machinery? Or we make a new array and run `rolling` over it?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,307783090

IIUC you need to copy a window-sized amount of data from the front of the array onto the back. 

You could do that with construct-like machinery, which would save a copy - though not a large copy","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,307783090

What do you mean by `rolling` here? As a reduce operation over a rolling window, like a moving average (`rolling` in xarray)? Or rolling around the end of a dataarray when shifting (`roll` in xarray)? Or a mix of both?

Specifically, what's the `dayofyear=31` doing?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,307783090
