> try and optimize duplication away (copy your data flow graph, but memoize and try to reuse) We sort of do that by hand at the moment. Rather than parametrise code, we attach ids to the data that is pushed through it. For example, instead of having a reusable 'compile' function we have a dataflow that just compiles anything thats added to the code tables and anything that wants to compile pushes code in one end and looks for the matching id coming out the other end. I'm not sure how far that will take us. It's certainly annoying when what you want is more like a function with a return value rather than a side effect. Still, we might be able to address that with a little sugar. We'll see.
