Examples

I mean, this looks pretty cool, right?

RomanNumeral I = "I";
RomanNumeral IV = "IV";

int a = IV - 1;
int b = 4 - I;
int c = IV - "I";
int d = "IV" - I;
int e = IV - I;

string f = IV - 1;
string g = 4 - I;
string h = IV - "I";
string i = "IV" - I;
string j = IV - I;

RomanNumeral k = IV - 1;
RomanNumeral l = 4 - I;
RomanNumeral m = IV - "I";
RomanNumeral n = "IV" - I;
RomanNumeral o = IV - I;
