+ * USAGE NOTE:
+ * https://stackoverflow.com/a/40523474/5533635
+ *
+ * If you're trying to pass apply() a variadic function, the compiler
+ * complains that it can't deduce the callable type, presumably because it
+ * doesn't know which arity to reify to pass.
+ *
+ * But it works to wrap the variadic function in a generic lambda, e.g.:
+ *
+ * @CODE
+ * LL::apply(
+ * [](auto&&... args)
+ * {
+ * return variadic(std::forward<decltype(args)>(args)...);
+ * },
+ * args);
+ * @ENDCODE
+ *
+ * Presumably this is because there's only one instance of the generic lambda
+ * @em type, with a variadic <tt>operator()()</tt>.
+ *
+ * It's pointless to provide a wrapper @em function that implicitly supplies
+ * the generic lambda. You couldn't pass your variadic function to our wrapper
+ * function, for the same original reason!
+ *
+ * Instead we provide a wrapper @em macro. Sorry, Dr. Stroustrup.
