I need to create many classes that are somewhere between integer and enum. I.e. have the arithmetics of integer but also are not implicitly converted to int.

Have a look at the answer to this question - BOOST_STRONG_TYPEDEF did exactly what I wanted.
// macro used to implement a strong typedef. strong typedef // guarentees that two types are distinguised even though the // share the same underlying implementation. typedef does not create // a new type. BOOST_STRONG_TYPEDEF(T, D) creates a new type named D // that operates as a type T.

One possibility is to create a class with the "enums" defined as invariant members of the class with a ::GetValue() method and the mathematical operations you need to use overloaded to use GetValue() to do the math in question.
