The parent comment is incorrect. Orthogonality is a really big deal in Go, and is highly stressed in the culture. Libraries are strongly encouraged to present methods that work with interfaces that are defined by the standard library to ensure the libraries are composable. If your library works with streams of bytes, its methods had better use io.Reader and io.Writer. If you're writing an ORM, it had better be built on database/sql.
