What would be a good implementation of iota_n (missing algorithm from the STL)

Question

With C++11, the STL has now a std::iota function (see a reference). In contrast to std::fill_n, std::generate_n, there is no std

Answer 1

A hypothetical iota_n

std::iota_n(first, count, value)

can be replaced by a one liner.

std::generate_n(first, count, [v=value]()mutable{return v++;})

I prefer this to have a lingering function that is not in the standard. Having said that, I think a std::iota_n should be in the standard.
