Sorry for the slow response. * The omitted string view functions all throw exceptions on bounds violatio= ns. * strtok_r is a posix function, not a c or c++ function. * I didn't want to change the semantics of programs across the freestanding= / hosted divide. So that is why rev0 of the paper deletes the at function.= I got feedback in abq that lewg does not want to remove portions of classe= s for freestanding... so all of array, string view, error code, etc... will= be removed in r1. * The random distributions I removed had floating point in the interface. I= did not remove all the distributions. I still need some implementation exp= erience to know if some of the distributions I kept use floats internally. * I will be sure to omit random stream operators in r1. * I will investigate seed_seq. * New classes that are freestanding friendly would be great, but I think th= at belongs in a different paper. Re: memcpy and friends. These functions are very useful, don't require space overhead, and don't re= quire is calls. That's why they are included. In practice, most existing em= bedded and kernel environments have optimized versions of these functions a= lready, demonstrating their usefulness and implementability. I did not ask "why should I include function x"? I asked "is there any reas= on not to include function x"? Other feedback I have received suggests that my removals may go too far. K= illing typeid in the library may be too much. I will likely make r1 focus m= ore on additions and less on removals. --=20 You received this message because you are subscribed to the Google Groups "= ISO C++ Standard - Future Proposals" group.
