          Sends a message to the destination with the content given.
  
          The content must be a type that can convert to a string through ``str(content)``.
          If the content is set to ``None`` (the default), then the ``embed`` parameter must
          be provided.
  
          To upload a single file, the ``file`` parameter should be used with a
          single :class:`~discord.File` object. To upload multiple files, the ``files``
          parameter should be used with a :class:`list` of :class:`~discord.File` objects.
          **Specifying both parameters will lead to an exception**.
  
          If the ``embed`` parameter is provided, it must be of type :class:`~discord.Embed` and
          it must be a rich embed type.
  
          Parameters
          ------------
          content: :class:`str`
              The content of the message to send.
          tts: :class:`bool`
              Indicates if the message should be sent using text-to-speech.
          embed: :class:`~discord.Embed`
              The rich embed for the content.
          file: :class:`~discord.File`
              The file to upload.
          files: List[:class:`~discord.File`]
              A list of files to upload. Must be a maximum of 10.
          nonce: :class:`int`
              The nonce to use for sending this message. If the message was successfully sent,
              then the message will have a nonce with this value.
          delete_after: :class:`float`
              If provided, the number of seconds to wait in the background
              before deleting the message we just sent. If the deletion fails,
              then it is silently ignored.
          allowed_mentions: :class:`~discord.AllowedMentions`
              Controls the mentions being processed in this message. If this is
              passed, then the object is merged with :attr:`~discord.Client.allowed_mentions`.
              The merging behaviour only overrides attributes that have been explicitly passed
              to the object, otherwise it uses the attributes set in :attr:`~discord.Client.allowed_mentions`.
              If no object is passed at all then the defaults given by :attr:`~discord.Client.allowed_mentions`
              are used instead.

          reference: Union[:class:`~discord.Message`, :class:`~discord.MessageReference`]
              A reference to the :class:`~discord.Message` to which you are replying, this can be created using
              :meth:`~discord.Message.to_reference` or passed directly as a :class:`~discord.Message`. You can control
              whether this mentions the author of the referenced message using the :attr:`~discord.AllowedMentions.replied_user`
              attribute of ``allowed_mentions`` or by setting ``mention_author``.
  
              .. versionadded:: 1.6
  
          mention_author: Optional[:class:`bool`]
              If set, overrides the :attr:`~discord.AllowedMentions.replied_user` attribute of ``allowed_mentions``.

          ~discord.Forbidden
              You do not have the proper permissions to send the message.
          ~discord.InvalidArgument
              The ``files`` list is not of the appropriate size,

              If a datetime is provided, it is recommended to use a UTC aware datetime.
              If the datetime is naive, it is assumed to be local time.
          around: Optional[Union[:class:`~discord.abc.Snowflake`, :class:`datetime.datetime`]]
