It is expected that named captures don't add new variables same as reserved words, and such variables couldn't be made usually at the time when named capture was implemented.

Keyword arguments since 2.0 can be the same as reserved words, however an assignment to an such already defined variable has been also suppressed now.

def test(s, nil: :ng)
  /(?<nil>.)/ =~ s
  binding.local_variable_get(:nil)
end
p test("a") #=> :ng

tap do |nil: :ng|
  /(?<nil>.)/ =~ "c"
  p binding.local_variable_get(:nil) #=> :ng
end
