var Semantic = conversion.EqualitiesOrDie(
	func(a, b resource.Quantity) bool {

		return a.Cmp(b) == 0
	},
	func(a, b metav1.Time) bool {
		return a.UTC() == b.UTC()
	},
	func(a, b labels.Selector) bool {
		return a.String() == b.String()
	},
	func(a, b fields.Selector) bool {
		return a.String() == b.String()
	},

Semantic can do semantic deep equality checks for api objects. Example: apiequality.Semantic.DeepEqual(aPod, aPodWithNonNilButEmptyMaps) == true
