These ports from Python and Ruby (like Martini, for another example) are well-intentioned, but I don't think they're a good idea to use. The original libraries get a lot of their expressive power from polymorphism - Requests gets a tremendous amount of mileage out of letting you pass in keyword arguments to the `get` method, for example.

Go prefers that you be more explicit and use more function declarations, even if it means repetition in the library code. When developers try to get around this, you see awkward constructs like the pointer-to-a-config-struct used here.
