Master Gorad asks his apprentice:

"How many statements does it take to call a function in Go ?

Apprentice replies puzzled "I can just call foo();" and I am done ?

Master Gorad beats his student with a cane. No, you silly, it takes at-least 3 statements to make a function call in Go:

    r, err := foo();
    if err != nil {
       return nil, err;
    }
