There's no two-argument version of operator[]. The "0,2" in "digit[0,2]"
will be read as a comma operator (thus discarding the first operand),
not as two arguments to a function. To use more than one argument you
have to use parentheses; operator(), unlike operator[], can be
overloaded for any number of arguments.
