+Paths can be denoted with various leading qualifiers to change the meaning of
+how it is resolved:
+
+* Paths starting with `::` are considered to be global paths where the
+  components of the path start being resolved from the crate root. Each
+  identifier in the path must resolve to an item.
+
+  ```rust
+  mod a {
+      pub fn foo() {}
+  }
+  mod b {
+      pub fn foo() {
+          ::a::foo(); // call a's foo function
+      }
+  }
+  # fn main() {}
+  ```
+
+* Paths starting with the keyword `super` begin resolution relative to the
+  parent module. Each further identifier must resolve to an item
+
+  ```rust
+  mod a {
+      pub fn foo() {}
+  }
+  mod b {
+      pub fn foo() {
+          super::a::foo(); // call a's foo function
+      }
+  }
+  # fn main() {}
+  ```
+
+* Paths starting with the keyword `self` begin resolution relative to the
+  current module. Each further identifier must resolve to an item.
+

+  fn foo() {}
+  fn bar() {
