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 referstransport.get_write_buffer_size(). However, I think the method name here should betransport.get_write_buffer_limits() because (1) corresponding short description is the one fortransport.get_write_buffer_limits() and (2) its counterpart,transport.set_write_buffer_limits() is listed just below.
