You seem to be making several arguments at once. My only point is that C# has no problem implementing java's Optional, which some other folks seemed confused about, and there are already libraries that do so. If there is a social/cultural issue too, I was not commenting on that, or commenting on the usefulness of checked exceptions.

Look how many people here are advocating for the nullable hack because they don't understand what an option is. With java the discussion could be side stepped entirely, since they added proper support and put it in the standard lib.

Again, you are arguing a different point than than one I was addressing.
