Not quite -- many numpy functions check for a method of the same name on their argument and call it instead of the numpy routine. If you look at the source of `np.sum`, it first checks for a `sum` method on its argument and calls that method instead if found. Otherwise, it coerces the argument to a numpy array and calls the numpy method.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,267826297

Can you explain? I don't think bottleneck is xarray aware, so I'm not surprised by this. NumPy doesn't have a generic interface for external functions (only [ufuncs](https://docs.scipy.org/doc/numpy-1.13.0/reference/ufuncs.html)).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,267826297
