Afaik, this has been brought up multiple times already and is so 
by design. Every aggregate has an init symbol, omitting that (and 
accordingly the default initialization of all instances) by 
initializing each field with void doesn't work. The 
initialization isn't performed fieldwise, but is a bitcopy of 
T.init.
You can skip initialization of specific instances though - `S s = 
void;` - but again not if `s` is a field of another aggregate.
