What does it do? What is the "trick"?
I feel like one of the answers in that thread:
"I hadn't heard of this trick before, is there an article somewhere
that explains the benefit of drawing bias current from V-? I feel like
there's something obvious that I'm missing."

I spontaneously found Aaron's idea potentially better than nothing,
but I haven't plunged into it.
