To be fair the "result"-part in "something you thought was an Option[T] result turned out to be really a T" makes it sound like you were speaking of the return-type to me as well. I appreciate the elboration though!

Yes, that was my fault, I overlooked "result," and I also appreciate the clarification.

I think the point remains that, while this is not a breaking change from a contractual viewpoint, most type systems would deem it incompatible.
