The code looks fine, but when do you need such a function? I can't think of a use case.
There's two main types of use cases: (1) geotagging actions you take on your computer, like git commits, for later analysis; and (2) writing software which varies its behaviour depending on your location, perhaps triggering useful events.
Okay, I agree these actually are good use cases ;)
