This article includes a statement I've seen several time before: "flux is more of a design pattern then a library or framework". This statement drives me to unspeakable levels of fury. What does that mean? It's like saying "Alvins ball is more a boulder in Yosemite than a mid century school of literary criticism". They're two totally different things! Someone who understands the statement, could you help me? Does it mean that there is a design pattern so light that some particular library which implants it would be trivial to recreate? Any answer, I beg you, please clearly distinguish between the very different concepts of design patterns and named code projects which implement them.
