+test: Simple Alias Example
+brief: >
+    If you need to refer to the same item of data twice,
+    you can give that item an alias.  The alias is a plain
+    string, starting with an ampersand.  The item may then
+    be referred to by the alias throughout your document
+    by using an asterisk before the name of the alias.
+    This is called an anchor.
+yaml: |
+    - &showell Steve
+    - Clark
+    - Brian
+    - Oren
+    - *showell
+php: |
+    array('Steve', 'Clark', 'Brian', 'Oren', 'Steve')
