-References in statics and constants may only refer to immutable values.
-
-Erroneous code example:
-
-```compile_fail,E0017
-static X: i32 = 1;
-const C: i32 = 2;
-
-// these three are not allowed:
-const CR: &mut i32 = &mut C;
-static STATIC_REF: &'static mut i32 = &mut X;
-static CONST_REF: &'static mut i32 = &mut C;
-```
-
-Statics are shared everywhere, and if they refer to mutable data one might
-violate memory safety since holding multiple mutable references to shared data
-is not allowed.
-
-If you really want global mutable state, try using `static mut` or a global
-`UnsafeCell`.
