Subject: [Q] clean way to print error & break from loop?

I would like an idiomatic way to print an error from inside of a loop and break from that loop in a single statement. I thought I could do something simple with "and" but it doesn't work with Kernel#puts due to #puts returning nil.

e.g.
loop do
  rc = do_some_work
  
  STDERR.puts "Work failed" and break unless ok?(rc)
end

I can get that example to work if I use "or" for flow control rather than "and" but it doesn't read right to me.

  STDERR.puts "Work failed" or break unless ok?(rc) # yuck

Any suggestions for a nice, clean, idiomatic way of accomplishing the above?
