You're refusing to define what a class is.. when I think the crux of the problem with this conversation is that we don't have the same definition. You think I'm using the word incorrectly. So please tell me what you think a "class" and what it is in relation to a "set/subsection"

there is no definition that you can attach to "class", that makes it correct for this usage, unless you want to change what the word means. Heres a good quote [1]:

> an expression /re/ can be used to specify a range of lines (matching the pattern), which can be combined with other commands

So the command contains a regex, but its not a regex itself, and its not a class of regex. Sorry, but you don't get to just say "well that's not my definition", and get out of it. Sometimes, you're just objectively wrong. It would be like saying you "donated" something, when you really "pledged" it.

You still fail to define what a "class" is simply because you didn't and don't understand it still.

https://math.stackexchange.com/a/173002 here read up. Also read on Russell's Paradox. I'm not objectively wrong you're just uneducated and your ego is too large. The irony is I was saying the exact same thing you were in my very first comment, except with more precision.

And I still would want you to think about what exactly "output" is.

you seem pretty smart about math, and pretty dumb about regular expressions. Considering that I have a RegEx bronze badge [1], I think I will just trust my own judgment in this matter.
