    You've already encountered Page Template expressions. Expressions
    provide values to template statements. For example, path
    expressions describe objects by giving them paths such as
    'request/form/age', or 'user/getUserName'. In this section you'll
    learn about all the different types of expressions, and variables.

       counterintuitive forward references. I believe this is pedagogically unsound. This whole chapter could well
       start w "Expressions".
