 template <Type Value1, Type Value2>
 using Plus2 = plusValue<Type, Value1, Value2>;
 /*...*/
};

Creates plusValue (see plusValue) acting on type Type. Allows for plusValue to act as binary value operator.

• Value1 - value to be summed with Value2.
• Value2 - value to be summed with Value1.

• value - holds result of addition of Value1 with Value2.

• value_type - type of field value. May not be Type but should be castable to this type.

• constexpr operator value_type () const noexcept - casts whole object to its value_type returning value.
