I have a class that holds arbitrary state and it's defined like this:
class AbstractFoo
{
};
template <class StatePolicy>
class Foo : public StatePolicy, public AbstractFoo
{
};
The state policy contains only protected attributes that represent the state.
The state might be the same for multiple behaviors and they can be replaced at runtime.
All Foo objects have the same interface to abstract the state itself and to enable storing Foo objects in containers.
I would like to find the least verbose and the most maintainable way to express this.
