If an operand implements method String() string that method
will be used for %v, %s, or Print etc.
Scanning:
An analogous set of functions scans formatted text to yield
values. Scan and Scanln read from os.Stdin; Fscan and Fscanln
read from a specified os.Reader. By default, tokens are
separated by spaces. Fscanln and Scanln stop scanning at a
newline and require that the items be followed by one; the
other routines treat newlines as spaces.
If an operand implements method Scan() (that is, it implements
the Scanner interface) that method will be used to scan the
text for that operand.
