This may be an interesting argument in whether we should remove "explicit" on multiple-argument constructors or not. I'm not sure though, how useful the ability to disallow direct initialization from a braced init list is. It's rather obvious what harm can an implicit call to a single-argument constructor cause, but with braced init lists a mistake is much less likely, imo. Matt, what do you think about this?
