> Russ discovered—that's the right word—that the generality of Go's methods meant that a function could have methods, leading to the http.HandlerFunc idea...more general ideas too, like the the io.Reader and io.Writer interfaces, which informed the structure of all the I/O libraries.

Big testament to great interfaces being hugely impactful. For me, the IO and HTTP interfaces are a big part of why Go is so nice to use; the libraries (including std) that emerged around those interfaces and their subsequent interoperability makes everything so coherent.

Congrats to the Go team and their amazing work!
