It seems possible that Rust could make better progress than C++ on incorporating this optimization into its standard library because it does not allow programmed move constructors, so "knows" more about its types. This is not assured, because it needs other declarative features that might not be in the core language yet, and might not be on the road map.

But running industrially important generic algorithms twice as fast as C++, automatically and without heroics, would be a Feather in Rust's Cap, and a Black Eye for C++. ("!!!!", as it were.) Or vice versa. Best would be if both got it, of course.

At present, both languages need heroics. I don't know of any other language where there is a reasonable prospect of getting such an optimization implemented generically, but that doesn't mean there aren't any.
