In simplest case, `break'ed iterator returns nil, otherwise
what will be returned depends on its specification and
implementation.  In this case, Integer#times returns self, so
you can write as:

  finished = 10.times {
    if some(condition)
      break
    end
  }
  if finished
    puts "iterated #{finished} times"
  else
    puts "breaked"
  end
