It *does* work. I *love* it :-D. But it requires at least partial C++11
support, does it not? My point was, I didn't see initializer lists on
the list of features to potentially use in examples.

Yes, different features. Sorry for muddying things :-). (Although I
personally am a fan of uniform initialization, I'm not arguing for its
use in examples... for one, I'm pretty sure it would further restrict
compiler support. If nothing else, there's a GCC bug as late as 4.8 at
least that references can't be {} initialized.)
