----------------------------------------
Bug #19190: `Regexp.compile('regexp', 'n')` raises `unknown regexp option: n (ArgumentError)`
https://bugs.ruby-lang.org/issues/19190
* Author: koic (Koichi ITO)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.2.0dev (2022-12-07T03:32:29Z master bcd8b2f00a) [x86_64-darwin19]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
I get the following unexpected error when using Ruby 3.2.0-dev.
## Expected (Ruby 3.1 and prior)
No errors:
```console
% ruby -ve "Regexp.compile('regexp', 'n')"
ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-darwin19]
```
## Actual (Ruby 3.2.0-dev)
An unexpected error occurs.
```console
% ruby -ve "Regexp.compile('regexp', 'n')"
ruby 3.2.0dev (2022-12-07T03:32:29Z master bcd8b2f00a) [x86_64-darwin19]
-e:1:in `initialize': unknown regexp option: n (ArgumentError)
Regexp.compile('regexp', 'n')
^^^^^^^^^^^^^
from -e:1:in `compile'
from -e:1:in `<main>'
```
## Context
I encountered the following error when developing the Parser gem with Ruby 3.2.0-dev. This is not encountered in Ruby 3.1.
```console
% cd whitequark/parser
% bundle exec rake
