'static in const and static references


Why are 'static lifetimes required to be written explicitly in const and static references?

const MY_STRING: &'static str = "Hello world!";
const MY_ARRAY_REF: &'static [int, ..1000] = &[0, ..1000];

If I understand the motivation correctly, the types should be written there explicitly for the similar reasons as for function declarations - they represent interfaces and shouldn’t change silently after changes to initializer or function body. But the lifetimes for const/static references are always 'static and will not change, can’t they be elided?

These explicit 'statics were relatively annoying before, with constant strings, but now they are even more annoying, because after introduction of const constant arrays have to be written through references.

const MY_ARRAY1: [int, ..1000] = [0, ..1000]; // Rvalue arrays are bad
static MY_ARRAY2: [int, ..1000] = [0, ..1000]; // `static` arrays can't be used in constant expressions
const MY_ARRAY3: &'static [int, ..1000] = &[0, ..1000]; // OK, but more verbose than necessary
