+/* Utilities for emulation of variadic template functions. Variadic packs are
+ * replaced by lists of BOOST_MULTI_INDEX_LIMIT_VARTEMPL_ARGS parameters:
+ *
+ * - typename... Args --> BOOST_MULTI_INDEX_TEMPLATE_PARAM_PACK
+ * - Args&&... args --> BOOST_MULTI_INDEX_FUNCTION_PARAM_PACK
+ * - std::forward<Args>(args)... --> BOOST_MULTI_INDEX_FORWARD_PARAM_PACK
+ *
+ * Forwarding emulated with Boost.Move. A template functions foo_imp
+ * defined in such way accepts *exactly* BOOST_MULTI_INDEX_LIMIT_VARTEMPL_ARGS
+ * arguments: variable number of arguments is emulated by providing a set of
+ * overloads foo forwarding to foo_impl with
+ *
+ * BOOST_MULTI_INDEX_OVERLOADS_TO_VARTEMPL
+ * BOOST_MULTI_INDEX_OVERLOADS_TO_VARTEMPL_EXTRA_ARG (initial extra arg)
+ *
+ * which fill the extra args with boost::multi_index::detail::noarg's.
+ * boost::multi_index::detail::vartempl_placement_new works the opposite
+ * way: it acceps a full a pointer x to Value and a
+ * BOOST_MULTI_INDEX_FUNCTION_PARAM_PACK and forwards to
+ * new(x) Value(args) where args is the argument pack after discarding
+ * noarg's.
+ *
+ * Emulation decays to the real thing when the compiler supports variadic
+ * templates and move semantics natively.
