I'd advocate for the following behavior :
1/ void member of tuple are computed, but not stored in the tuple.
2/ A tuple with one member can unpack automagically.

With both, I'm pretty the code broken is close to none.

To go further, I advocate for declaration to be expression. It would 
allow (int a, int b) = foo();

Which rox, as Andrei said :D
