I can see where you're going with this, but as others have noted I don't think
it's really the right way to go about it.
If the property hooks RFC passes (we're stalled a bit trying to put together
benchmarks, sorry), that will solve this use case in a much cleaner and more
generic way. (A property could be virtual, and backed by arbitrary logic to do
all the same streaming that you're talking about here.)
