.. and final comment for today, I missed that this only value-initializes "c2"
if it has a default constructor! Since it doesn't have a default constructor,
8.5.4 will not hit bullet p3bullet1, but p3bullet2 because "C" is an aggregate
class. As a consequence, I believe aggregate initialization happens and the
initialization of c2 is well-formed this way too.

Shouldn't comment this late in the day. Perhaps I missed something again :)
