Hi, I am wondering if there is a construct in boost which, given a type T, returns the underlying "storable" type - say if T is int & the "storable_type" should be int. I'm not sure if the word "storable" is the best word... The scenario I am facing is making a function call that takes a parameter of type T, where I need to prepare the parameter before calling (specifically, deserializing it from an archive). Hence, as far as I can tell, I need to declare a variable of the underlying storable type, and get the right value inside it. So far, I've been using: template<typename T> struct storable : public boost::remove_const<typename boost::remove_reference<T>::type > {}; but I'm not sure if that cuts it in all situations. In any case, I figured the right thing might be in Boost already and I just haven't found it. Any suggestions? Thanks! Stjepan
