I'm not sure the derivative really makes sense. I would either error
or leave it unevaluated.

In PR #13204 I encountered the question of what to do with the derivative if
a Boolean. A Boolean is true or false but may contain expressions within
relationals, For example, `x**2 < y` depends on x and y but the Boolean
value is a "square wave" for this relational. Does a derivative wrt x or y
even make sense? Should an error, 0 or something else be done for a return
value?
