I will include that consideration, thanks; I am not hell-bent on it either way - there's some value in having paren-initializing aggregates mean exactly the same thing as brace-initializing them, but there's also some value in having paren-init not prevent narrowing. Turning off narrowing prevention makes some sense to me, but I can live without it. I can also easily imagine some user somewhere saying "no, don't do that, I intentionally left out constructors with the expectation that my type can *not* be initialized with narrowing conversions, and just because it can now be initialized with a syntax that wasn't ok before should not change that without my opt-in". ;) -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
