Is there an example of a node that iterates through several indices while requesting the appropriate indexed data from a node wired to a iteration node's in port?
Thanks!

Could you clarify what you mean? An example? (The answer is of course "no" by definition, since there are no GV examples at all, but if I understand what you mean I might be able to help... :-)

Well, I am trying to create a node that cycles through a loop executing for each index. Seems like those ITERATE enumerations running around in the headers would elude to an iterate functionality within the nodes. Is there a possibility of an example sometime? ;-)

Here's an example that outputs seven iterated vectors. It's a bit useless at the moment, since not very many nodes expect an iterated stream of vectors alone, but it should show the main principle.
