Maybe that's the point. If you implement, say, arrays very badly, and call them arrays, then everyone can easily criticize you in very direct terms: "Flunk has arrays, but they are broken compared to Python arrays, or even C arrays and Fortran arrays". The left-most "arrays" in that sentence can be a straightforward, blue-underlined link directly to the Flunk documentation which describes arrays. But if you call then batteries, then such a comparison gets confounded with distracting explanations. It's harder to argue that Flunk has broken arrays, when it has something called batteries that hold cells which have polarity and whatnot. First you have to argue that they really are just arrays under a different name, then you have to argue why they are bad compared to arrays, and why that still matters in the context where they are batteries. By the time you're done, you look stupider than Flunk, and more negative than the (-) end of a Flunk battery.
