[Scan] (that is, it implements the [Scanner] interface) that
method will be used to scan the text for that operand.  Also,
if the number of arguments scanned is less than the number of
arguments provided, an error is returned.

All arguments to be scanned must be either pointers to basic
types or implementations of the [Scanner] interface.
