Why do you think Rust is applicable, here? It isn't obvious to me that these people would benefit from a language that can be used anywhere that C++ can be .

Why do you need lambdas/closures in order to have function composition? Don't you just need higher order functions? The thing about map id = id etc. probably has more to do with equational reasoning (can use equals to substitute t

The MLs seem to have better module systems. Or, they have a module system.

I don't think that being a so-called metrosexual has anything to do with gender identity. There are probably a lot of metrosexual men that don't self-identify with femininity any more than the average man. As far as divorcing biol

In order for someone to be a "beta male", it implies they are being competitive, too. They are just less successful than the "alpha males". "Metrosexual" is just a more PC way of calling men who care a lot (rel

It would be cool to see a comparison between AOP and the monad stacks of Haskell.

Prolog is the kind of language that is sold on being declarative, but ultimately you have to study how the unification algorithm works. And probably also sprinkle cuts around your code in order to not let the runtime do too much work, or ma

It's the language for an introductory course, so it's purpose is more of a gateway language than as a be-all-end-all language. Rust would probably be too strict and annoying as a first language. Maybe the same is the case for Hask

To be fair, couldn't you use java's foreach instead of the regular for-loop? It makes things a bit less noisy.

Well that's what I said. Being a really good instrumentalist has little to do with popular success. I deliberately chose the word "instrumentalist", not "artist". I don't understand why you start with "Yes

Being an exceptionally good instrumentalist is not how you get to become a world famous rock band (or band in general). If that were true, people like Steve Vai would be more famous than Slash and Guns and Roses.

It's asinine to write about and promote such a result as "10,000 hours"[1] when the result was really that it varies a lot from skill to skill. Using some constant number like 10,000 gives exactly the idea that there is som

It might be that it could serve the niche in which code has to be really performant, and you also need "complete" (to a strict degree) safety guarantees, and Rust can not give enough guarantees in that regard (and it is unacceptab

I think I saw some proposal to replace the function composition from prelude (.) with some other symbol, and presumably making it illegal to define operators named (.). This would of course break a lot of code, but it seems simple enough to

Darn, forgot about that one. ATS does seem to get considerably less mention than Rust, which may be because of marketing and/or because it is even more scary than Rust (dependent types, oh my).
