It looks like the Scheme version of Flow-based Programming (aka dataflow programming) or hardware synthesis. Not sure how well that works for general software but Paul Morrison led a lot of work using it in industry (eg banking apps). It&#x27;s also made a comeback in recent years for acceleration of software, optionally with hardware engines.<p>So, could an expert in these things tell me what this paper innovates or offers over mature Flow-based programming&#x27;s way of doing things?
