I started using this branch in a project the other day, and my classes tied to Rails had really clean calls to `env.foobar`, while my plain-ol' Ruby classes had to call `Dotenv.env.foobar`. It felt like I was being punished for writing code that was not coupled to Rails.

I've felt this pain with other libraries in the past too, and I don't have any good ideas to solve this besides adding methods to `Kernel`. Rails creates a negative feedback loop.
