+/**
+ * A weak reference implementation for Steinberg FObject.
+ *
+ * Implementation
+ * ==============
+ *
+ * This takes over the ordinary addRef() and release() methods.
+ * The variable `refCount` is accessed manually, under a shared mutex.
+ * There is a unique data block which is shared with all weak pointers, the
+ * system will null it atomically when the reference count hits zero.
+ *
+ * Usage
+ * =====
+ *
+ * class MyObject : public FObject, public Weakable<MyObject> {
+ *   [...]
+ *   WEAKABLE_REFCOUNT_METHODS(MyObject)
+ * };
+ *
+ * WeakPtr<MyObject> ptr = myObject.getWeakPtr();
