Everyone is allowed to give their own meaning to words, but you can't expect to just change a widely agreed meaning to match it. "Static" means it is just a set of files. Not that the page is stationary. Do you think that a blink tag in a HTML page makes it non-static? A hover effect? An :after pseudoelement in CSS?

If your perl script is saving the HTML to the disk, then yeah, your website is static. If it's generating HTML on the fly, it's dynamic. That's the widely agreed upon meaning, and that's it.
