I have nothing against the blocks&amp;arrow model. I just find it [sometimes horribly] inefficient.<p>For instance, in a video-compositing application (something like nuke - to put a name) it makes sense, especially so you can represent&#x2F;preview the state of the filter in the block itself, but it&#x27;s far from being an efficient method to <i>input</i> or manipulate. If you have experience by programming in any classical language with a grammar, it should be self-evident.<p>I find myself thinking I could represent the same graph in a much more compact and logically structural way using a written grammar, albeit doing that loses some given visual aspects like previewing.<p>I was explicitly asking if there is anything <i>else</i> available.
