[issue12797] io.FileIO and io.open should support openat

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

I prefer a new parameter either at the end of the arglist or possibly keyword only. The idea for both variations is to let typical users ignore the option, which would be hard to do if it is part of the prime parameter. The idea for keyword only is that we might want to add other rarely used but useful options. They have no natural order, and having say, 8 positional params is pretty wretched. (I have worked with such APIs.)
