This allows us to easily make function calls that have parameters that are dependent
upon converting from msgpack objects to concrete types. For example:
void process_args(std::tuple<int,std::string>& args)
{
...
}
process_args(obj.convert(std::make_tuple(100,"hello")))
You can get similar behavior by using obj.as<...>() but its performance is highly
dependent upon the specific compiler and whether or not r-value references are
supported.
