Re: Run something only once in a while loop?
The explicit purpose of the feedback node is to retain information for another run of that diagram expression. The complication is specifying what the lifetime is for the retained state data -- when is it to be initialized and with what value. The initializer terminal on the feedback node and the left side of the shift register are there to specify the value and timing of the initialization. Perhaps it doesn't work the way your intuition says it should, and I'd like to hear more about that, but it seems pretty complete, useful, and teachable. I'd like to hear the cases you are having issues with.
