As part of JEP 477 and JEP 495 (Simple Source Files and Instance Main Methods) we've introduced a new IO class to provide an extremely simple I/O APIs. This includes a new point in the namespace, a "readln" method to read a line of input, which is a nice counterpart to println. Perhaps unfortunately, the BufferedReader method to read a line is "readLine". In order to reinforce the symmetry with various println methods, we should also introduce a "readln" method to BufferedReader as an alias for readLine.
