-Contains few tests on qualified paths where a type parameter is provided at the end: `type A = <S as Tr>::A::f<u8>;`. The tests check if this fails during type checking, not parsing.

 ## `tests/ui/query-system/`
 
 Tests on Rust methods and functions which use the query system, such as `std::mem::size_of`. These compute information about the current runtime and return it. See [Query system | rustc-dev-guide](https://rustc-dev-guide.rust-lang.org/query.html).
