Agenda+ to ask about whether I should keep negative-zero tracking within an expression.  (The distinction will disappear when it exits a top-level calculation, at the same time as NaNs disappear.)

Specifically, should `calc(1 / calc(1/(-1/0)))` produce positive infinity or negative infinity?  If negative-zero is tracked, the the inner calc produces negative zero, and the outer calc then produces negative infinity. If it's not, then the inner calc just produces zero, and the outer calc produces positive infinity.
