Hmm, yes. My post there is this one:
I want to point out that in my code the single consumer of a Queue is
incredibly common, so common that I can't off the top of my head think
of _any_ uses of Queue directly: I _always_ make an IterableQueue and
simply have the consumer iterate over the iterable queue.
This is _exactly_ like Vladimir's proposal to my mind: my IterableQueue
is iterable, and has a .close method just like his (prevent further puts
and indicates end of stream) mediated with a sentinel internally.
Arbitrary number of putters, _usually_ only one getter but of course
there's no need for that.
So to my mind his proposal is very simple and sensible, and matches
almost universally my own use of Queues.
