-# `const_indexing`
-
-The tracking issue for this feature is: [#29947]
-
-[#29947]: https://github.com/rust-lang/rust/issues/29947
-
-------------------------
-
-The `const_indexing` feature allows the constant evaluation of index operations
-on constant arrays and repeat expressions.
-
-## Examples
-
-```rust
-#![feature(const_indexing)]
-
-const ARR: [usize; 5] = [1, 2, 3, 4, 5];
-const ARR2: [usize; ARR[1]] = [42, 99];
-```
