slidingWindowC makes consuming tail elements inconvenient

There's not really enough here to understand the request. But for this kind of case it sounds like a ZipSink usage with lastC may be relevant.

In the end I ended up writing this function:

slidingWindowWithTailC :: Monad m => Int -> ConduitT a [a] m ()
slidingWindowWithTailC sz = do
  xs <- slidingWindowC sz .| sinkList
  yieldMany xs
  when ((sz > 1) && (not $ null xs)) $
    yield $ tail $ last xs

It's not exactly pretty but it did the job for my case. I'll just close the issue, I'll leave it up to you to reopen it if this would seem useful in general.

Keep in mind that this will read all the elements into memory, losing any advantages of streaming the data.
