Basically just replaced `SharedString::new("` with
`SharedShring::new_static("` which removes the allocation to `Arc<str>`.
Unfortunately this can't be enforced at compile time without trait
specialization which is only available on nightly. You could assert that
`TypeId`'s differ, but `TypeId` only exists at runtime.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
