C#'s IObservable<>/IObserver<> made me think how would a dual

IObserver<> part which relates to a D range.
Ranges/enumerators are models of 'pull' style interface
whereas their
duals represent models of 'push' style enabling reactive
programming [3]
techniques which are really nicely solving issues of
asynchronous /
event - based programming.
I suppose OutptRange is similar in concept, although it has
'OnCompleted' / 'OnError' missing.
What do you think? Rx along with LINQ is a really clean
solution to the
problem of asynchronous ranges of values. I think it would be
very nice
to have in D too.

In case you are interested, I have thrown together a small
proof of concept implementation:

Wow, that is now what I'd small ;) I will definitely take a look.
Is it something you already had written or something new? How do
you feel about the concept?
