Well, you're not doing anything wrong. That section of the proposal
was meant to be a "if the initializer lists proposal is accepted,
then it would act like this." I didn't actually mean to propose any
changes to the initializer syntax, and so I didn't implement them.
(That said, it's a relatively simple feature to implement, if we need
it to test something out).
