+AD4- I had proposed before that all 'for' loops should have an implicit variable '+AF8AXw-i' keeping count of the iterations, something like:

+AD4- for ( auto +ACY-e : my+AF8-vector ) SomeFunc( e, +AF8AXw-i )+ADs-


The standard already has that - that's what std::views::enumerate() provides.

And there's std::views::iota() if you only want a counter.

And the rumor is C+-+-26 will have std::views::upto(). (from https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1894r0.pdf)
