Actually, I've used your method (not sure if it *is* yours, but I saw it
in serialization code) for cases where it wouldn't compile on the false
branch. In the linked example, there are 4 cases, but same idea as I
think where you used it in serialization.

The idea is something like this:

template<typename T>
void do_whatever_impl(boost::mpl::true_) {

template<typename T>
void do_whatever_impl(boost::mpl::false_) {
   // no T::whatever()

template<typename T>
void do_whatever() {

PS: I know I have to change to make_shared, just too lazy right now.
