I created the D version of the value type exceptions proposal. In the end, it was DOA due to compiler architecture, so that was the end of that beautiful design. I've had to accept result types is about as good as its going to get, all that is missing to make them nice is unwrapping support in if statements. Which I too have a proposal for and implemented it. But alas politics.
