async def delete_messages(self, messages):
        """|coro|

        Deletes a list of messages. This is similar to :meth:`Message.delete`
        except it bulk deletes multiple messages.

        As a special case, if the number of messages is 0, then nothing
        is done. If the number of messages is 1 then single message
        delete is done. If it's more than two, then bulk delete is used.

        You cannot bulk delete more than 100 messages or messages that
        are older than 14 days old.

        You must have the :attr:`~Permissions.manage_messages` permission to
        use this.

        Usable only by bot accounts.

        Parameters
        -----------
        messages: Iterable[:class:`abc.Snowflake`]
            An iterable of messages denoting which ones to bulk delete.

        Raises
        ------
        ClientException
            The number of messages to delete was more than 100.
        Forbidden
            You do not have proper permissions to delete the messages or
            you're not using a bot account.
        HTTPException
            Deleting the messages failed.
