Expressions are an important element of the language. There are many types of expressions. The expression rule in the compiler is the biggest rule
The table below lists the various expression types in the order they are recognized by the compiler. Some expression types are covered in a separate topic.
As you can see most expression types are recursive. They contain one or more references to sub expressions
