 I think the main conclusion here should be that defining a ctor taking an
std::initializer_list should be done only after careful consideration and
never at all if adding it introduces a risk of ambiguity with an existing
ctor. It's unfortunate that a class used as commonly as std::vector doesn't
follow this rule, but we'll just have to live with it.

 But in the absence of std::initializer_list-induced complications using {}
still seems like the best choice to me.
