Some example code that triggers this lint:

```rust
#[allow(dead_code)]
type SendVec<T: Send> = Vec<T>;
```

This will produce:

```text
warning: type alias is never used: `SendVec`
--> src/main.rs:1:1
warning: bounds on generic parameters are not enforced in type aliases
--> src/lib.rs:2:17
|
1 | type SendVec<T: Send> = Vec<T>;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2 | type SendVec<T: Send> = Vec<T>;
| ^^^^
|
= note: #[warn(type_alias_bounds)] on by default
= help: the bound will not be checked when the type alias is used, and should be removed
```
