I think the problem here is what's the type of digit[0]?  If it's
like arrays, then digit is rank2, digit[0] is rank1, and digit[0][2]
is rank0.  On the other hand, if you claim that all are rank 0, then
how do you distinguish whether the i in Parser::operator[](int i) is for the min
or max repititions of *this?
