in reply to Modules, Frameworks, and Reinventing the Wheel
This touches on the larger issue of learning programming with high level languages coupled with large code repositories. The new student often learns the basics, well or not so well. Then it all grinds to a halt. Theses days the idea of writing your own code as a beginner becomes moot since you're constantly advised not to re-invent the wheel. 'Trouble is, how else do you become proficient with a language if you don't write code with it? Now the wheel has been perfected what is there to do? New programmers inevitably end up doing nothing more than marveling at the design of someone else's code.
Another issue is quality control for CPAN. How do new students know if a module is any good?
