如何在关注中添加多个包含的块？

Question

一切都说明如下：

# below is a common lib definition.
module SomeLib
    extend ActiveSupport::Concern

    included do
        puts 'executing predefined block from lib'
    end
end

# I want to expand the lib through my logic 
module SomeLib
    # errors: ActiveSupport::Concern::MultipleIncludedBlocks 
    included do
        puts 'executing some actions defined by me'
    end
end

那么如果在该模块中定义了一个额外包含的块，该如何定义？
