Shortcut: from environs import env

[AndBondStyle]

I've been using envparse package for a very long time, but discovered "environs" just moments ago. Your package is obviously better in many cases, but I really miss one feature from the old one: the global default Env class instance that can be imported by from envparse import env. I think it's really convenient to use and makes the code just a little bit neater than env = Env() (which is probably used like this in 99.9% of times).

What do you think about this feature? It shoud be possible to make it absolutely zero-cost by using some proper module-level __getattr__ trickery. Also, it would be perfect to have another "exported" instance that's equivalent to env = Env() + env.read_env().

I wouldn't be opposed to exporting a singleton env. I wouldn't make it automatically run env.read_env(), though. I don't believe that would be an expected import side effect.
