Because Larry Wall, the inventor and still current authority over the language Perl says so?
I still don't grasp what the issue is. Someone creates something; someone updates their thing into separate tracks; ...
I guess what I don't understand is why some people are so fundamentally angry about it. I would love to have all of the arguments laid out logically. Who cares what the new language is called realistically. I don't understand how it affects some people emotionally. It could be called (taking a quip out of "American Gangster") "Blue Dog Shit".
What's the difference? Why the hatred? Why does one care? What ties does one have to the name "Perl" that makes one so angry?
