Creating rulex has been quite a journey, during which I learned a lot about regex syntax, its quirks, and the differences between various regex flavors. I already knew a lot about regexes before I started this project, but creating a language that compiles to regexes requires a much deeper and more thorough understanding of them. I didn't create rulex so I don't have to master regexes. I created it so that people who use it don't have to master regexes -- a language that is riddled with poor design choices. Yes, you can get used to it, just like you can get used to working with a dull plastic knife. The fact that people need a website such as regex101 or regexr just shows, in my humble opinion, that regular expressions aren't as straightforward or easy to understand as they could be.
