Thank you for the thoughtful reply. I do in fact agree it is probably unreasonable for people to expect automatic code generation to be hand-editable without disturbing the machine-editable workflow, but it is something that comes up a lot.
I see that Google's tool also seems to produce rather inscrutable output (see my edit to my original post). This does sound like one of those really hard problems where is pretty much impossible to balance the needs of the machine-modifiability with human-readability.
Thanks again for the reply!
