I was referring to grouping parentheses. Most uses of "$" are for stupid
things like "sin $ 1 + 2" where parentheses would be much more clear. By
"beginning of time" I thought it was clear I meant "I don't feel like
looking it up," but thanks -- we now know that people have been using
parentheses about 400 years longer than "$" for grouping.
