certain meta characters shouldn't be allowed in char ranges

[andruo11]

When I parse the regex /[\w-z]/ it should throw an error, but instead parses as a regular character range with \w at the beginning. https://astexplorer.net/#/gist/124dd2c7d464e3cf68b532bf8dacae7f/01a86f60e792112367c9395cf1094b5806dcaab1 If I figure out how to fix it I'll let you know!

...and ditto for Unicode properties like /[\p{P}-z]/u

Thanks for the report, yeah, the /[\w-z]/.test('-') should actually be parsed as a char class containing \w, - and z.

Is your reference another parser in the AST explorer, or JS itself? and if JS, how do you know the internal structure? My parents think I should learn more about this topic, and if I’m going to help out, I should probably figure out how to make a good pull request.

Seems /[\p{P}-z]/u is at least throwing now even while /[\w-z]/ isn't.
