Thanks for the link, your approach looks simpler, which is nice.  As you
said, the workflow is a little bit different: Your package prettifies
every regular expression at once and mine does so on a case by case
basis; I think it's a matter of preference.  I also prettify the final
rx form to make it more readable.

I didn't know about the easy-escape package.  I see it was suggested to
be included in Emacs core around 2017, but there were no responses back
then.  Maybe we could have this kind of functionality at least in ELPA?
I think it's a generally useful package.
