The feed through method seemed promising, with the arrow pointing to its pair on the right. It could look like a tunnel but inherit the nature of a shift (typo, haha) register, applicable for loops and non-loop structures. If only the terminal is smaller...
Too bad I am not at my workstation now, otherwise would have cook up something...
how about this? a tunnel that can be converted into a "feed through" tunnel by a right click, "replace with feed through", just like a shift register. each "feed through" will exist in pairs distinguishable by different height in the BD. and it will default the left writer wire value, unless it is wired on the right.
can also be considered for enforcing dataflow sequence, like a error wire, transforming the structure as if it was an opened subVI. cases with error terminals can read and update the feedthough, cases without can inherit the cluster without additional case by case wiring. no more clutter.
yeah... the png is supposed to have a version for the case type structures as well, but for some reasons unknown, I can't upload it. reason I use the arrow, rather than bar within the box, is to intuitively show the shift register's N=0 behaviour inherited by the tunnel. having it resemble much to the conventional tunnel may lead to misunderstanding that common tunnels have the same behaviour...
The bar was just to indicate a change. I'd prefer an arrow or at least some other graphics as well. I just didn't want to spend time on something that might never happen.
>the png is supposed to have a version for the case type structures as well,
No idea what you mean by that, getting curious now.
In your example you wired one of the new tunnel outputs. This will make it act exactly like a normal tunnel, right?
