* Author: tompng (tomoya ishida)
* Status: Closed
* Priority: Normal
* ruby -v: ruby 3.2.0dev (2022-08-29T15:47:09Z :detached: cd7506593a) [x86_64-linux]

Ripper does not seems to recognize regexp named capture defining new local variables, fails to parse some code.
~~~ruby
requie 'ripper'
# expect syntax ok, got syntax error
Ripper.sexp("/(?<a>)/ =~ ''; x = a **a, a if false")
# expect syntax error, got syntax ok
Ripper.sexp("/(?<a>)/ =~ ''; x = a **a, **a if false")
# "exit" is a method call, got string_literal
Ripper.sexp("/(?<a>)/ =~ ''; a %(exit)")
