Doesn't this go against the "literals are enclosed in quotes" idea? In this case, you have a special character (`-`) inside a quoted string. IMO this would be more consistent: `['0'-'9''a'-'f'']`, maybe even have comma separation like `['0'-'9','a'-'f'']`. This would also allow you to include the character classes like `[d,'a'-'f'']` although that might be a little confusing if you're used to normal regex.
Thanks for reading and taking the time to respond!

Sure, one could argue that other changes would also be useful, but then it would be less concise. I think the main reasons why people like regex are: (a) powerful, (b) concise.
For my V2 proposal, the new rule is: "literals are enclosed in quotes", the rule isn't "_only_ literals are enclosed in quotes" :-) In this case, I think `-` can be quoted as well. I wanted to keep the v2 syntax as close as possible to the existing syntax.
