Stabilize `const_raw_ptr_deref` for `const T` This stabilizes dereferencing immutable raw pointers in const contexts. It does not stabilize `mut T` dereferencing. This is placed behind the `const_raw_mut_ptr_deref` feature gate. 2021-10-05 03:55:57 -05:00			`//~^ ERROR dereferencing raw mutable pointers in constants is unstable`
