My guess (guess!) it will actually have better performance than 
generating new template body for every member field. That 
template bloat can easily get out of control to the point of 
negative performance impact. As I have already mentioned, we 
don't do that for nested aggregates - and this one is not that 
different.

I do favor you first proposal actually but it requires some 
considerations about fitting concept into language design 
(despite being easy to implement).
