如果我们相信数据结构，就必须相信独立的（因此同时进行）处理。为什么我们还要在结构内收集物品？我们为什么要容忍一种语言而没有另一种语言呢？
If we believe in data structures, we must believe in independent (hence simultaneous) processing. For why else would we collect items within a structure? Why do we tolerate languages that give us the one without the other?
Purely applicative languages are poorly applicable.
