Naming conventions for constants in Go: CamelCase, ALL_CAPS, or something else?

Hi everyone! I've just started learning Go after Python and C#, and I'm a bit confused about the naming conventions for constants. In Python we usually use `ALL_CAPS` for constants: `MAX_CONNECTIONS = 100`. In C# it's common to use `PascalCase`. But in Go, I see different code in different projects. For example, in the Go standard library I came across these examples: ```go // In the http package const ( MethodGet = "GET" MethodPost = "POST" ) // In the os package const ( O_RDONLY = 0x0 O_WRONLY = 0x1 ) ``` The first example uses CamelCase (`MethodGet`), and the second uses snake_case with uppercase letters (`O_RDONLY`). When I asked a colleague, he said that in Go you should use `CamelCase` for exported constants and `lowerCamelCase` for unexported ones. But then why does `os`
