I would also suggest a third thing that needs to be looked at:
alternative syntax. Because as Christof noted, `{1, 2}` and `{1, 2;}`
are very different things under this idea, yet they do not immediately
appear to be. It's not entirely difficult to write the wrong one in
some location using `auto` deduction that just so happens to compile.
`{}` notation within certain locations already means "initialize an
object", so having syntax that's so similar means something so very
different is probably something that should be looked at closely.

That is, if braces really are the best syntax for this, it'd be good
to have an examination of what the not-best syntaxes are to establish
why they're the best.
