 The default constructor is only auto-generated if there is no user-declared constructor, hence it's impossible to initialize the vector `vd1` in the example above.

 `Date` is chosen to encourage thought:
 There is no "natural" default date (the big bang is too far back in time to be useful for most people), so this example is non-trivial.

 If `Foobar` couldn't be opened for writing and `out` wasn't set to throw exceptions upon errors, the output operations become no-ops.
 The implementation must take care of that case, and users must remember to test for success.
