I think it's a really ingenious idea, but haven't yet found myself wanting
to use it. Would you mind describing how you've used it in more detail? I
would appreciate seeing the motivation.

I think we need to have a version submitted that at least one person has
found useful, and we need to have at least one person review that version
before we can do that.

Why don't you submit your throwing version of stream_cast? If we can find a
review volunteer, with luck we can make the official addition.
