I think that this is something that you can get accustomed to pretty quickly. Vectorised operations and broadcasting are very common across languages too, it's not just the python data stack that uses them. A more weird but still basic example from pandas is the way it handles indexing and the confusion between .loc, .iloc, .ix, .at and plain '[]'. That part of the API should be really basic but for some reason it's a giant mess.
