Would be amazing if you could support certain types of iterative operations IE you have a list element and you apply a certain filter substituting in each element from the list.

One example would be the "social graph" node, which takes only a single did. It would be cool if you could apply that node over a list rather than manually specifying each did.

Similarly it could work well for supplying a parameter list and then scanning for each type of content one after the other.
