Me too :-)

My co-author included a section in one of her chapters of our
recent book, and I duly played with them while reviewing that
chapter. But at the end I just deleted it all and
thought "Hmmmm....?"

I know why they are useful in theory, but I've never found
a practical use for them myself.
