Custom "Struct" connections for Cycles shading graphs

Hi all, Given that Cycles procedural shading networks get more and more complex, I think it would be a great productivity and efficiency boost to be able to combine multiple labeled values to customizable "Struct" node, pass them on to other modules as a single connection holding all the values, and then separate (break) the values for use using a corresponding separate-struct node. I actually do this today using the Combine and Separate Vector nodes, to bind data together into a single connection so its easier to handle and also keep the shading graph cleaner. But I think we should be able to define an expendable struct holding multiple labeled floats and vector values, kind of like a "brother" to the Group node, in which you can define inputs and will have a single output the passes all the combined data. The workflow can be that you define such a custom struct node similarly to the way we define Group nodes with their inputs, but here the list of labeled values is not "inputs" or "outputs" but simply the data members the struct holds with their labels. and then for every instance of the node use, you can set it to either combine input values and output one compound data output, or separate one compound connection to its individual components, so naturally you will only be allowed to connect the combined output of a Struct node to the combined input of another instance of the same Struct node. Hope I managed to explain the idea... I added a crude illustration of how it might look.. Thanks! Oded
