Bug #20091: Anonymous block method parameters no longer usable within blocks with ruby 3.3

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [amd64-freebsd13]
• Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN

This used to work on 3.1 and 3.2, but now fails with "anonymous block parameter is also used within block (SyntaxError)":

def g = yield

def f(&)
  g { g(&) }
end

p f { 123 }

And something like this also fails:

def f(&)
  loop do
    return g(&)
  end
end
