Querying the template allows you to be able to create another layer of abstraction between the code and the template. We use it to create a custom 'TemplateLoader' that will look at a given template, and by the naming convention that we use on the vars and loops it will actually create the SQL statements, query the database and load the templates. The only thing we have to remember is to use the nameing convention for the vars. This works for about 95% of the occassions that we use H::T and then the other %5 we use it more straight forward. The benefits of this are that if we want to add some more data to the template (an extra column or field or something) we just add the correct TMPL_VAR to the template and then the TemplateLoader does the rest. We don't have to change the code. If you're curiosity is piqued, then you can check out how we do this at cheesepizza.venzia.com. The module in question is named 'CheesePizza::TemplateLoader'.
