One great use of named tuples would be named function arguments. I've grown tired of seeing functions that take a bunch of doubles and always checking which arg

  This would be a case where C99 style designated initializers would come in handy in C++. For example if you have a struct like: struct data { double w; double x; double y; double z; }; You can then create a struct of that type using syntax like: struct data d = {.w = 1.0, .x = 1.0, .y = 1.0, .z = 1.0}; Then you could have your functions take a struct data as a parameter, and use designated initializers to have syntax for keyword parameters. I'm not sure why this feature never made its way into a C++ standard over the years.

    Don't forget that you can also have functions return a struct.

  I'd rather have something like Strong Typdef for that. Maybe we will get it eventually. http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p0109r0.pdf http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p010...
