        Good day to everyone! Is there some reason why call_traits<SomeEnum>::param_type evaluates to be the const_reference (const SomeEnum&) instead of value_type (SomeEnum)? I can't figure out if its an easily fixable mistake in the library or a result of some consideration that's not quite obvious. Any advice is greatly appreciated. Leo.
