Rich Hickey's "Maybe Not" should be watched by anyone who thinks nulls/nils/undefineds are okay.

说明
这是2018年由ClojureTV发布的一部演讲,主题归在Programming language design。它讲的是type systems and data modelling这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Rich Hickey's Clojure/Conj 2018 keynote argues that Maybe/Option types and rigid type signatures are a poor way to model data that changes over time. He builds the case around optionality, schema growth and compatibility, and presents the ideas behind Clojure spec as an alternative.这些读者给出的理由,核心是:HN commenters send people to it whenever nulls, Maybe/Option or static typing come up, as a thoughtful dissent from the type-system orthodoxy that changes how some people model data.讲法不绑某一条新闻,过几年仍然可以当材料看。从2018年到2025年,有14位不同的读者在11个不同月份把它推荐出来,其中明确叫别人去看的有5次。适合一次性看完。讲者把一个判断讲透,演示是在给这个判断配例子。如果已经会了基本定义,就把注意力放在它怎么把type systems and data modelling变成能跟着复述的例子。
