Although I like currying a method, I think it makes things difficult. Think about it, you joined an ongoing project and see curried functions and variables around. You have to check each function if it's curried from another to find original function (in this case `volume` function) and that might be exhausting. Without proper documentation for every curried function, it might be time consuming.
