Well, if List<T> is invariant on the T, then you cannot usefully have lists parameterized on interfaces, which is losing a useful ability. I'd say that classifies as a thorny edge case. In Haskell, I can represent the type: (Sho

If you have a class Sub implementing an interface IBase. How does C# handle the case of List<Sub> being used as List<IBase>? If it is allowed, does it let you do: List<IBase> base = subList; base.append(someOth

The edge cases regarding generics have to do with the mixing of inheritance subtyping and generics. The ML family have working generics and they work well. Go made the good decision of avoiding sub-typing, so they should not have a serious

Opaque types like "Integer" don't give a lot of assurance, so either you get a stronger type system (Agda-style) or you have to test. But complicated code may work with non-opaque types, and so it could still be reliable without tests.

Git is a very simple and powerful system covered by a hideous and complicated CLI. The simplicity is simply hidden.

On a touch screen, you only have two primitive gestures from which all gestures are composed: Taps and swipes. Composition may be chronological or simultaneous (multi-touch). This space of gestures is so narrow, that any idea within it can

Haskell has tuples, so it could use an: (a, b) -> c representation. If the uniform/canonical way to use functions is defined to be curried, then flip can simply return them curried.

They seem to simply be missing flip. // Lets curry subtract instead of add var subtract = Udon.curry(function(a, b) { return a - b; }); var five_minus = subtract(5); var minus_five = Udon.flip(subtract)(5)

If you want to write functions that are polymorphic on any monad, they'd have to take a type argument explicitly, which also reduces their cost-effectiveness. I am not sure Monads are a cost-effective abstraction in most languages.

Generalizing Monad in a language without return-type polymorphism is hard. How do you implement "return" (unit)?

[foo, bar, baz, quux] might be problematic if the types of these functions are not homogenous. foo >=> bar >=> baz >=> quux is ok and >=> is not a much-worse separator than , here...

Exceptions can be modeled by a type like "Maybe" that simply also has the error information in it. So instead of a "Nothing", you have "Left err" with the "err" information in it. The nice thing is that the same example using >>= ab

Again, you refuse to acknowledge that Grads are used. You put words into my mouth. You fail to engage in minimally-honest debate. This does not belong on Hacker News, and we probably both have better things to do.

Claiming Grad rockets are "home-made" and implying they are not a deadly threat (when in fact the reason they killed few people is the Israeli warning system and extensive bomb shelters).

You said "home-made" rockets. True or false?

The post you're replying to is completely factual . His claim was an oft-repeated lie. I corrected it. Apologizing for lies is a litmus test for an honest debater. There's no point debating someone who would lie and when corrected, would y

You've just dodged the subject and went on to talk about something else. Will you first admit that your claim about "home made" rockets or small amount of deaths are inaccurate and misleading? There's no point in debating with someone who's

They may not attack fishermen, but they do kill Israeli families, fire rockets at Israeli civilian cities, and otherwise engage in horrific violence towards Israeli citizens. How could it not be at anyone's expense? There is no free and ope

I am an Israeli - and am quite disheartened that you are bringing /r/worldnews style comments to HN. Let's keep it focused and avoid the useless flame wars, shall we? Whether you agree with Israel's actions or not, it needs its nukes to sur

For Israel, the nukes are almost a survival necessity. Nukes in the hands of Israel are less worrying to many than nuclear technology (that could be translated to nuclear weaponry) in the hands of a theocracy. Additionally, the Palestinian

Didn't Ruby have dynamic scoping in day 1? Dynamically scoped lambdas are different lambdas, and much less useful.

In Haskell, sortBy takes a comparison function: sortBy :: (a -> a -> Ordering) -> [a] -> [a] And Ordering is defined as: data Ordering = LT | EQ | GT If you want to provide a "key" function rather than a compar

No, that's false -- consider the Maybe case. If you carry around the content of the Maybe, it will still remain valid even after the Maybe itself is overwritten. Races are of course still possible but they don't relate to boolean blindness.
