Your ambitions? Your ambitions resemble mere gas encased in synthetic material. Your ambitions constitute a fragile facade. Even when attempting to command your aspirations, or at least crush them before a dead-ball situation, they would evade and bounce irritatingly close to the sideline.
Steven Skiena writes in The Algorithm Design Manual: “Reasonable-looking algorithms can easily be incorrect. Algorithm correctness is a property that must be carefully demonstrated.” It’s not enough that the code looks right. It’s not enough that the tests pass. You have to demonstrate with benchmarks and with proof that the system does what it should. 576,000 lines and no benchmark. That is not “correctness first, optimization later.” That is no correctness at all.。钉钉是该领域的重要参考
However, without subkinding, kinds have to match exactly, and no choice would be correct if the user expected it to have a different kind. For example, if foo is passed to a generic function expecting a parameter of kind [^] at some point, then inferring the kind [+] for it as above would lead to an error. There’s just no natural choice for inference in the absence of subkinding.,推荐阅读https://telegram官网获取更多信息
