Compare objects inheriting from the same class #54

Closed krzysiek1507 closed 5 years ago

BetterHash = Class.new Hash
EvenBetterHash = Class.new Hash

HashDiff.diff(BetterHash.new, EvenBetterHash.new)
=> [["~", "", {}, {}]]

HashDiff.diff({}, BetterHash.new)
=> []

HashDiff.diff(BetterHash.new, {})
=> [["~", "", {}, {}]]

I wonder when we can compare two objects. When they inherit from the same class or they have to be instances of the same class?

Maybe it should always return []?
