There is a DR filed against the C++14 draft that says std::min/max etc should be constexpr.
Hopefully that will get resolved next month in Issaquah.

Nah. It’s easy to write a std::min replacement that is constexpr (assuming that operator < is constexpr).
That’s what __min in string_view is; it just would be better if it could use std::min.
