Notation The syntax is specified using a variant of Extended Backus-Naur Form (EBNF): Ah, the good ol’ Extended Backus-Naur Form… EBNF is a fairly popular way to formally describe a formal language. There’s a very good chance you’ve seen something like this before, especially if you’ve ever found yourself reading an RFC. But if you haven’t, this is a great time to familiarize yourself with the basic concepts. I won’t go into a detailed explanation of EBNF or WSN (the variant used in the Go spec), as there are better online resources.
