   - `all`: if all variables in destructuring should be const, this rule warns the variables. Otherwise, ignores them.
 - `ignoreReadonly`: If `true`, this rule will ignore variables that are read between the declaration and the _first_ assignment.
+- `excludedRunes`: An array of rune names that should be ignored. Even if a rune is declared with `let`, it will still be ignored.
