-/**
- * A template class that provides a way to defer the initialization of an object until its value is
- * actually required. This is also commonly referred to as lazy initialization.
- *
- * Dangers:
- * - This implementation is currently not thread safe, and it shouldn't be used in multi-threaded
- *   fashion.
- * - Be careful about using this for lazy initialization of data members and capturing the 'this'
- *   variable. Code like this will result in buggy/unsafe move constructors, which would have a
- *   dangling reference to the moved-from type:
- *
- *   class MyType {
- *       int x;
- *       // !!! Dangling 'this' when moved !!!
- *       Deferred<int> xSquared{[this]() { return this->x * this-> x; };
- *   };
- *   Instead, it is better to do something like this:
- *   class MyType {
- *       int xSquared() const {
- *          return *_xSquared.get(_x);
- *       }
- *
- *       int _x;
- *       Deferred<int, int> _xSquared{[](int x) { return x * x; };
- *   };
- * - As a similar danger, the value is only computed once. if you initialize it with arguments like
- *   the above 'xSquared()' implementation, then be cogniscent that the value will never change. If
- *   '_x' changes, '_xSquared' will not.
- *
- * A Deferred class can be constructed with either an initial value (eager initialization) or a
- * function that will generate the value when needed.
