Yep, you are that old ^_~
In modern development one can go through an entire project without using any of the language's standard libraries or even, in extreme cases, the language itself. If you ever want to see a frightening example of this gone too far, take a look at over uses of Apache Camel or even Spring, where you can write entire systems using code embedded in XML files and that weird 'conditional logic as constructor arguments' camel allows for.
