 % Universal Function Call Syntax
 
-Sometimes, functions can have the same names. Consider this code:
-
-```rust
-trait Foo {
-    fn f(&self);
-}
-
-trait Bar {
-    fn f(&self);
-}
-
-struct Baz;
-
-impl Foo for Baz {

-}
-
-impl Bar for Baz {
-    fn f(&self) { println!("Baz’s impl of Bar"); }
-}
-
-let b = Baz;
-```
-
-If we were to try to call `b.f()`, we’d get an error:
-
-```text
-error: multiple applicable methods in scope [E0034]
-b.f();
-  ^~~
-note: candidate #1 is defined in an impl of the trait `main::Foo` for the type
-`main::Baz`
-    fn f(&self) { println!("Baz’s impl of Foo"); }
-    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-note: candidate #2 is defined in an impl of the trait `main::Bar` for the type
-`main::Baz`
-    fn f(&self) { println!("Baz’s impl of Bar"); }
-    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-```
-
-We need a way to disambiguate which method we need. This feature is called
-‘universal function call syntax’, and it looks like this:
-
-```rust
-# trait Foo {
-#     fn f(&self);
-# }
-# trait Bar {
-#     fn f(&self);
-# }
-# struct Baz;
-# impl Foo for Baz {
-#     fn f(&self) { println!("Baz’s impl of Foo"); }
-# }
-# impl Bar for Baz {
-#     fn f(&self) { println!("Baz’s impl of Bar"); }
-# }
-# let b = Baz;
-Foo::f(&b);
-Bar::f(&b);
-```
-
-Let’s break it down.
-
-```rust,ignore
-Foo::
-Bar::
-```
-
-These halves of the invocation are the types of the two traits: `Foo` and
-`Bar`. This is what ends up actually doing the disambiguation between the two:
-Rust calls the one from the trait name you use.
-
-```rust,ignore
-f(&b)
-```
-
-When we call a method like `b.f()` using [method syntax][methodsyntax], Rust
-will automatically borrow `b` if `f()` takes `&self`. In this case, Rust will
-not, and so we need to pass an explicit `&b`.

-# Angle-bracket Form
-
-The form of UFCS we just talked about:
-
-```rust,ignore
-Type::method(args);
-```
-
-Is a short-hand. There’s an expanded form of this that’s needed in some
-situations:
-
-```rust,ignore
-<Type as Trait>::method(args);
-```
-
-The `<>::` syntax is a means of providing a type hint. The type goes inside
-the `<>`s. In this case, the type is `Type as Trait`, indicating that we want
-`Trait`’s version of `method` to be called here. The `as Trait` part is
-optional if it’s not ambiguous. Same with the angle brackets, hence the
-shorter form.
-
-Here’s an example of using the longer form.
-
-```rust
-trait Foo {
-    fn clone(&self);
-}
-
-#[derive(Clone)]
-struct Bar;
-
-impl Foo for Bar {
-    fn clone(&self) {
-        println!("Making a clone of Bar");
-
-        <Bar as Clone>::clone(self);
-    }
-}
-```
-
-This will call the `Clone` trait’s `clone()` method, rather than `Foo`’s.
