If you could write all your applications without recourse to an editor, version control software, a browser or other software to access CPAN, a datbase, test tools and all the other tools and utilities that the average perl programmer uses to write his applications, then I would agree with you, but you can't.

Oh but I could. It would take longer probably and be harder to implement, but thats why they invented all these nifty automated utilities to speed up production of the product, isn't it?
