Visual for-loops work just fine for iterating over geometry chunks, and can even be parallelized with "compile block begin" nodes in Houdini. High-level iteration is less intuitive, eg. iterating over random seeds for a sim and rendering preview animations, but the process is still easier than switching the entire thing to text input. The toolkit for this is called PDG or TOP networks.
