I'm pretty sure it was made by an autistic person.
Who the hell thought that something that looks like this...

^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$

... would code validation for an email address? How the fuck is that readable by a non autistic?

Here is how I would write that in a readable way
{::Any::}@{::Any::}.{::Any:2-4:}

I'm not really going to argue very much ...
... but as something tends towards being very specific (and your example is a little ambiguous, right - what's an "Any" for example) so it gets more and more mad.

Some of it looks like line noise, I'll totally agree though. Ctrl-Alt-Palm, and there you go, instant regex ...
