I could not find a way to check whether or not a given value belongs to an interval expressed as RealRange (or a union of them e.g. RealRange(Open(-10),-5), RealRange(Open(-6),infinity).

Ideally, I would like a Boolean function that takes two arguments (i) a value v and (ii) a (union of) RealRange r, and returns true/false depending on whether or not value v is in/out of the range r.
