int main()
{
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template plus<> == 0u, "zero should be 0");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template plus<42u> == 42u, "42 should be 42");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template plus<22u, 20u> == 42u, "22 + 20 should be 42");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template plus<42u, 0u> == 42u, "42 + 0 should be 42");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template plus<10u, 12u, 20u> == (10u + 12u + 20u),
 "10 + 12 + 20 should be 42");
 static_assert(crap :: arithmeticOperatorsForType <unsigned int> :: template plus<20u, 0u, 0u, 0u, 0u, 0u, 0u, 22u> == 42u,
 "anything plus 0 remains seme so rest should be 42");
