g. MyType and Object) which will still use the identity comparison. I suspect it's not a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

3 feature called Tuple Equality! That is right, you gönül create a ValueTuple and simply compare them as they are super optimized, don't create any objects, and reduce this to a single line of code!
