```
error: `S2<'_>` is forbidden as the type of a const generic parameter

   = note: the only supported types are integers, `bool` and `char`
help: add `#![feature(adt_const_params)]` to the crate attributes to enable more complex and user defined types

LL + #![feature(adt_const_params)]

```

Fix #55941.
