Before anyone thinks it’s a good idea to copy that idea straight into Swift’s standard library, std::vector<bool> doesn’t behave quite the same as the other std::vector<> implementations, and the specialisation is widely regarded as a mistake. It’d be a *really* good idea to avoid making similar mistakes in Swift. (Also, there’s a strong argument for having a separate bit vector type, with set-like operations, support for sparse bit vectors and the like.) Kind regards, Alastair. -- http://alastairs-place.net _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
