A portable, modern regular expression language
I had a similar kind of idea for a long time, which I put into action a few weeks ago via a standalone transpiler of Emacs' rx macro to common regexp syntaxes.[0] I ended up getting interrupted and didn't completely finish it, but it generally works, though is probably riddled with edge cases.
The basic idea of rx is to use S-expressions to describe regular expressions, and my elevator pitch would've been to embed rx invocations in shell scripts using $(syntax), the main use case being something like sed invocations.
I still think it's a neat idea, and complex regular expressions tend to be hard to parse for humans.

A portable, modern regular expression language
I agree with you. I got tired of fighting with regex where I got to the point of simply not using it if at all possible.
A comment further up offered a very promising alternative.

It's a bit verbose, but I don't care anymore, I am too much a veteran to care about my code being sleek, I want it readable and workable.
