Yeah, I get that it's valid Perl code, but it doesn't cause the computer to do something, or give an interesting output. A human can read it and find it interesting. I tried to say that in a witty way. Oh well...

It not doing anything isn't the point. The point is that it's technically valid code, but is still relevant to human interpretation.
This was the point I was trying to make.
It not doing anything matters - generally, code poetry is something that does do something interesting while being relevant to human interpretation; so code that simply validates syntactically isn't that amazing.
