-An unstable feature in `const` contexts was used.
-
-Erroneous code example:
-
-```compile_fail,E0723
-const fn foo<T: Copy>(_: T) { // error!
-   // ...
-}
-```
-
-To enable this feature on a nightly version of rustc, add the `const_fn`
-feature flag:
-
-```
-#![feature(const_fn)]
-
-const fn foo<T: Copy>(_: T) { // ok!
-   // ...
-}
-```
