I played with that a little and now I have:

template <class T, class R, R (T::*p)>
char const *get(T const &self)
{
   return self.*p;
}

class_<foo>("foo")
   .add_property("bar", get<foo, char[4], &foo::bar>);

I wonder if there is a way to somehow get rid of specifying char[4] and 
probably foo manually.
