 Controls structures, like if, for, foreach, and while can be written in
 a simplified format as well. Here is an example using foreach::

-endforeach. Each of the control structures listed above has a similar

 Also notice that instead of using a semicolon after each structure
 (except the last one), there is a colon. This is important!
