> It might confuse the future developers when they use OpenHashMap.apply() with
> a numeric value type.
> null.asInstance[Int], null.asInstance[Long], null.asInstace[Float] and
> null.asInstance[Double] will return 0/0.0/0L, which might confuse the
> developer if the value set contains 0/0.0/0L with an existing key
