I'm suggesting that Push returns, conceptually, two things: an iter.Seq, and a pair of functions. You hand the iter.Seq off to something that expects an iter.Seq. You use the two functions to push values into the iter.Seq. Just as iter.Pull gives you flexibility to fetch values from the sequence however you like, iter.Push gives you flexibility to push values into the sequence however you like, without being tied to the lifespan of a single function. In the original example, the values to push into the sequence would come from a method call. This can all be done already with channels, of course, as shown by the earlier examples.
