They cannot be same.  I would surprise if calling Proc#[] terminates
meow().  But I prepared the way to make meow behave as you expect:

  def meow(doyield, &block)
    puts "in meow #{doyield}"
    if doyield
      yield
    else
      block[]
    end
    puts "leaving meow"
  rescue LocalJumpError
    return
  end

  b = Proc.new {
    puts "in proc"
    break
    puts "leaving proc"
  }

  meow(true, &b)
  puts
  meow(false, &b)

Tip: do not use "proc" nor "lambda" when you want objectified Block.
