This one has been allowed since the first commit of rustc-demangle adding the v0 demangler.

* [[#39] Add support for `min_const_generics` constants](https://github.com/rust-lang/rustc-demangle/pull/39)
* [[#40] Elide the type when the const value is a placeholder `p`](https://github.com/rust-lang/rustc-demangle/pull/40)
* [[#55] v0: demangle structural constants and &str.](https://github.com/rust-lang/rustc-demangle/pull/55)
(only usable in `const` generics on unstable Rust)
* **(UNPORTED)** recursion limits
* miscellaneous
* **(UNPORTED)** extraneous symbol suffix (e.g. `.llvm.*`) removal
* **ported** PRs:
* [[#30] v0: also support preserving extra suffixes found after mangled symbol.](https://github.com/rust-lang/rustc-demangle/pull/30)
* **(UNPORTED)** output size limits
