It takes the somewhat contrarian view that writing dataflows directly is unnecessarily restrictive, and by doing so we lose abstractions we have come to rely on in most modern high level languages (control flow, composability, recursion, high order functions, etc). redun's key insight is that workflows can be expressed as lazy expressions, which are then evaluated by a scheduler that performs automatic parallelization, caching, and data provenance…
