It would be lovely if readlines() took a parameter to specify the number
of lines to return:
line1, line2 = io.readlines(2) # Doesn't work :-(
but alas and alack, the readlines() method has exactly the wrong API for
that. I don't know what use the hint parameter is for readlines, it
seems totally useless to me, and the wrong abstraction, counting
bytes/characters instead of lines.
Maybe we could add a keyword only argument?
line1, line2 = io.readlines(count=2)
Or there's always the explicit:
line1, line2 = [io.readline() for j in (1, 2)]
No need for new syntax for something so easy.
