So you are suggesting that using concepts of optionals is not a good idea?
Yeah. But had to narrow down as it mentioned "Supreme Court"
"You cannot step twice in the same river". One can step into the same river more than once since one can commit the same mistakes over and over again. However had the quote been "You MUST not step twice in the same river", then the quote would have made sense. That way the quote becomes prescriptive not to commit the same mistake.
