Added on the branches:
+/**
+ * <luaT_tuple_encode_table>() reference in the Lua registry.
+ *
+ * Storing of the reference allows to don't create a new GCfunc
+ * object each time we call the function in the protected mode.
+ * It reduces Lua GC pressure in comparison with calling of
+ * <lua_cpcall>() or <lua_pushcfunction>() on each invocation.
+ */
static int luaT_tuple_encode_table_ref = LUA_NOREF;
