"Conditional Append" at array indexing tunnel

Compare the upper loop(old) with the lower loop(new).
Take a close look at the loop exit.



Solution: Right click the indexing tunnel and select "Enable Conditional Append"

This works not only with FOR-Loops. 


History: This idea was already presented by me in May 2008

Yes, this definitely needs to be a per-tunnel setting (and the question mark wasn't originally mine, it appears in the original illustration. I agree that it might be better not to have it).


Also, I've since learned that Jeff's suggestion can actually be done today. Feedback nodes have the ability to add a conditional terminal, thus allowing that to happen. I still don't like it, though.

Try to take over the world!
