Scala: checking if an object is Numeric

Is it possible for a pattern match to detect if something is a Numeric? I want to do the following:

class DoubleWrapper(value: Double) {
  override def equals(o: Any): Boolean = o match {
    case o: Numeric => value == o.toDouble
    case _ => false
  }
  override def hashCode(): Int = value ##
}

But of course this doesn't really work because Numeric isn't the supertype of things like Int and Double, it's a typeclass. I also can't do something like def equals[N: Numeric](o: N) because o has to be Any to fit the contract for equals.

So how do I do it without listing out every known Numeric class (including, I guess, user-defined classes I may not even know about)?
