To me a story is a series of features working together to explain how the developer will actually interact with things. It's not unlike Agile's definition, but maybe more practical? Languages and developer environments are a product, so considering them as the sum of their parts from a UX perspective is very healthy.
So when I say, "you use channels for concurrency" this is not strictly true (technically the concurrency primitive is goroutines, as someone corrected to me above). But since it's a practical consideration that you need to use channels (and your race condition detector will flip out if you don't), I say "you use channels". It's a useful fiction.
I used to call these Wittgenstein's Ladder because I'm a huge nerd but no one ever understood the nature of the joke and so I started speaking relatable english again. :|
