> Enter Golang... a language smaller than even ANSI C. It's readable because if you've worked with Golang for more than a week, you basically know every language construct you'll encounter.

That's not really what readability is to me. For example, I consider this idiomatic golang code (from the standard library, no less) to be entirely unreadable:

https://golang.org/src/crypto/tls/handshake_messages.go#L297

For me readability is more about suitable levels of abstraction. Languages can affect that by making abstraction longwinded, or expensive at runtime, or hard to compose.
