Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @pcwalton (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see CONTRIBUTING.md for more information. |

Adds `<module::Type>::method` support and makes `module::Type::method` a shorthand for it. This is most of #16293, except that chaining multiple associated types is not yet supported. Unfortunately, this is still a *[breaking-change]*: * If you used a global path to a primitive type, i.e. `::bool`, `::i32` etc. - that was a bug I had to fix. Solution: remove the leading `::`. * If you passed explicit `impl`-side type parameters to an inherent method, e.g.: ```rust struct Foo<T>(T); impl<A, B> Foo<(A, B)> { fn pair(a: A, b: B) -> Foo<(A, B)> { Foo((a, b)) } } Foo::<A, B>::pair(a, b) // Now that is sugar for: <Foo<A, B>>::pair(a, b) // Which isn't valid because `Foo` has only one type parameter. // Solution: replace with: Foo::<(A, B)>::pair(a, b) // And, if possible, remove the explicit type param entirely: Foo::pair(a, b) ``` * If you used the `QPath`-related `AstBuilder` methods @hugwijst added in #21943. The methods still exist, but `QPath` was replaced by `QSelf`, with the actual path stored separately. Solution: unpack the pair returned by `cx.qpath` to get the two arguments for `cx.expr_qpath`.

Adds `<module::Type>::method` support and makes `module::Type::method` a shorthand for it. This is most of #16293, except that chaining multiple associated types is not yet supported. It also fixes #22563 as `impl`s are no longer treated as modules in resolve. Unfortunately, this is still a *[breaking-change]*: * If you used a global path to a primitive type, i.e. `::bool`, `::i32` etc. - that was a bug I had to fix.
