```ruby
module Discordrb::Events
  class MessageEvent
    attr_reader :message

    def initialize(message)
      @message = message
    end

    def author; @message.author; end
    alias_method :user, :author
    def channel; @message.channel; end
    def content; @message.content; end
    alias_method :text, :content
  end

  class MessageEventHandler
    def initialize(attributes, &block)
      @attributes = attributes
      @block = block
    end

    def match(event)
    end
  end
end
```

Add matching logic for MessageEventHandler
user
```ruby
module Discordrb::Events
  class MessageEvent
    attr_reader :message

    def initialize(message)
      @message = message
    end

    def author; @message.author; end
    alias_method :user, :author
    def channel; @message.channel; end
    def content; @message.content; end
    alias_method :text, :content
  end

  class MessageEventHandler
    def initialize(attributes, &block)
      @attributes = attributes
      @block = block
    end

    def match(event)
      # Check for the proper event type
      return false unless event.is_a? MessageEvent

      return [
        matches_all(@attributes[:starting_with], event.content) { |a,e| e.start_with? a },
        matches_all(@attributes[:ending_with], event.content) { |a,e| e.end_with? a },
        matches_all(@attributes[:containing], event.content) { |a,e| e.include? a },
        matches_all(@attributes[:in], event.channel) do |a,e|
          if a.is_a? String
            a == e.name
          elsif a.is_a? Fixnum
            a == e.id
          else
            a == e
          end
        end,
        matches_all(@attributes[:from], event.author) do |a,e|
          if a.is_a? String
            a == e.name
          elsif a.is_a? Fixnum
            a == e.id
          else
            a == e
          end
        end,
        matches_all(@attributes[:with_text], event.content) { |a,e| e == a }
      ].reduce(false, &:|)
    end
  end
end
