// DEPRECATED in favor of adl_postconstruct with deconstruct<T>().
// A simple framework for creating objects with postconstructors.
// The objects must inherit from boost::signals2::postconstructible, and
// have their lifetimes managed by
// boost::shared_ptr created with the boost::signals2::deconstruct_ptr()
// function.
