Boost :

    I am trying to create a library for type erasure(for boost if there
is enough interest). I would like to define some common operations
like arithmetic, I/O &c. For some of these I want to use Boost.Operators
to provide the other related operations. I am also, however, using
inheritance in order to allow several operations to be combined.
This for example is the definition of incrementable:

namespace erasures {
  struct incrementable : operation<incrementable> {
    template<class T>
    struct static_impl : implementation<void (T&)> {
      static void execute(T& t) { ++t; }
    template<class Base>
    struct partial_interface :
      *boost::incrementable<typename Base::erasure_full_t, Base>* {
      typename Base::erasure_full_t& operator++() {

Is use of base class chaining in this way part of the public API
of Boost.Operators? - Base may not be related to Boost.Operators
in any way. Or should I use multiple inheritance instead?

In Christ,
