In the "Write Transports" table in the Transports section of asyncio low-level API index page, invalid method name is listed. In that table, the second row from the bottom currently refers transport.get_write_buffer_size(). However, I think the method name here should be transport.get_write_buffer_limits() because (1) corresponding short description is the one for transport.get_write_buffer_limits() and (2) its counterpart, transport.set_write_buffer_limits() is listed just below.
