Exactly. I don't know where the confusion is, but I'm saying that it doesn't matter how the page is generated. It is sent to the website visitor as just HTML. When the user views it it is all there, just html. No changes.
For example, I have a perl script that generates a set of .html files every night to show new additions to my library. They are static .html files on disk and never modified before the user views them. Just because a perl script (not connected to the web server in any way) made it does not "taint" the HTML so it is not static. The program, or the person, that wrote the HTML does not matter. All that matters is that it's just static unchanging HTML.
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.
