--- Comment #40 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Matthew Woehlke from comment #39) > So? People have been asking for it for at least *13+ years* (this report was > opened in August 2002). Compared to clang which has had this feature for > some years already, gcc is lagging. Unfortunately, Clang has more developers working on just its C-family FE than GCC has developers working on all C-family, Ada, Fortran FEs plus middle-end (optimizations, LTO) and all its back-ends combined. Thus, lagging behind Clang w.r.t. C++ features is normal. What is your solution? (In fact, it is only a testament to how hard GCC C++ developers work that the gap is not much wider.) > I do hope so, but given that a) it hasn't been implemented in over a decade > of people asking for it, and b) isn't actually required for conformance, I'm > not holding my breath. Features get implemented when someone implements them. People implement features because a) they get paid for it (are you paying someone who is not delivering?) or b) they have the time and motivation to do it (do you think this is important enough to dedicate your time to implement this?). If the answer to those questions is no, then this cannot be such a critical feature, since nobody has bothered to get it implemented (or paid to do so) in the last decade.
