+//
+// life_guard is a convenience which takes advantage of
+// std::enable_shared_from_this<T>. The life_guard glorifies the constructor
+// of an std::shared_ptr<T> by accepting std::weak_ptr<T> and T& itself all
+// with proper semantics. Once construction is successful, the user holds it
+// for the duration of the scope ensuring T& survives context interleaving
+// without being destructed.
