Methods are part of the type, not of the value. It is perfectly safe to call methods on a nil value.

Read function at net.go is like this:

func (c *conn) Read(b []byte) (int, error) {
    if !c.ok() {

the ok checks that c is non nil:
func (c *conn) ok() bool { return c != nil && c.fd != nil }

how can c ever be nil ? if it would c.ok() call would crash.
