IMHO we need to keep working on the "tuple-like" concept so that there is *no reason* to write the above instead of: struct QGradientStop { double position; QColor color; }; I don't think we're there yet. There are (apparently) still cases where QPair/std::pair/std::tuple is more useful than a struct. If we can make that no longer the case, I hope we can stop (ab)using those for cases that a struct is more appropriate. -- Matthew -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
