It's chaining functions with a dot, just like you do in typical OO languages. When it's OO, it's a virtue that everyone loves - a "fluent interface". When it's FP - oh it's unreadable! Why don't they

Other way around. Step 1 of Raft is for the distributed nodes to come to consensus on a fact - i.e. who the leader is. ALL of Paxos is the distributed nodes coming to consensus on a fact. Raft just sounds easier because its descriptions u

Nah I think I'd just prefer to figure out the types in type-checking phase, then erase and get on with things. I don't buy that most polymorphism is dynamic. No example of 'new T()' (which wouldn't be improved by

Exactly. If they agree, then there was no point to introducing a second source of truth. If they disagree, then which one do you trust?

Hackers can add weight to an aircraft as fast - if not faster - than formally-trained engineers. As long as we keep measuring LOCs or features added, there will always be jobs for them.

Audit tables are a dumb concept because they imply bolting on an actual source of truth in addition to the regular not so source of truth tables , and only if the programmer gets around to it (like documentation or logging or whatever el

I don't know if you're referring to a particular language's peculiarities, but it doesn't really matter. It's mutation. tombert's point (I think) is that in a functional setting, factorial(n) is always facto

It's implied by void-returning do-something-with(...). Otherwise you're just burning cycles and a good compiler should dead-code eliminate the whole loop. (see https://news.ycombinator.com/item?id=44873488 )

Nope. Loops are unnecessary unless you have mutation. If you don't mutate, there's no need to run the same code again: if the state of the world did not change during iteration 1, and you run the same code on it again, the state

Once they've been converted from free variables to formal parameters then it's assumed you can just stack allocate them, and roll them off when you return from your lambda (which is no longer a closure)

Given that Hack had generics as early as 2014, it seemed that those who were worried about PHP being stuck were right. Unless I'm misunderstanding what this proposal (not finished artifact) is about.
