No, but Haskell does not need to explain monad for that either. All examples and docs for map/concatMap over a list are free from having to mention any type class at all. On the other hand, if you have to explain how the for/yield

What I meant to say is that the abstractions are definitely there in zio, which was meant to address your first comment where you said that zio did not have them. By reading the docs I could easily recognize monads. If you replace “for” wit

I took a look at ZIO ( https://zio.dev/guides/quickstarts/hello-world ) and just the first example explains a monad. That first example shows that the for syntax desugars to nested flatMap. Which is analogous to Has

The latest update to Amazonka (the Haskell library for AWS) was 3 hours ago. https://github.com/brendanhay/amazonka I use the package directly from GitHub in my project.

Sounds like you are taking about ReaderT, which is a common way of implicitly passing more data to functions. There are many other ways, though.

Our experiences differ, then. I have found it to be more easy to refactor and parallelize that other languages I have used. Debugging has not been difficult either, but I have always use print debugging in every language, so there is not mu

You may use the optics package instead. It is a replacement for the lens octaves with a focus on good docs and better error messages: https://hackage.haskell.org/package/optics-0.1/docs/Optics.h...

You can do enable strict evaluation by default in Haskell, though. So, that must not be the reason why the language is not mainstream. More likely, network effects can explain how something makes it to the mainstream. For example having a b

Yes, there is GHCi, the Haskell interpreter and repl comes bundled with the compiler. You can load your entire project in the repl and try your functions there.

The motivation for Haskell included building large applications. It was not solely a research language, but the culmination of years of research in non strict functional languages: https://www.haskell.org/onlinereport/p

Most of the popular languages in use today have big corporations backing them. I would say that this is a major reason why Haskell and other niche programming languages are not more widely adopted.

Haskell is a great language for imperative programming, actually. You are not limited by the language in that regard.

You can use the LiquidHaskell plugin to perform extra compile time checks to numeric code.

At this point there is not difference between the two of them. GHC is Haskell for all practical purposes

Haskell is such a language. You can enable strict evaluation on a per module basis, or for an entire package.

You can make any module strict by using the XStrict language pragma in Haskell.

This sounds like haskell’s backpack, which lets you swap implementations of a model interface at will. But maybe I’m misunderstanding what you meant. Polymorphism is front an central to everything in Haskell, which is why your comment sound

One of hadolint authors here. You can do `apt-get install my_package==4.1.*`, for instance and that will pass the validation and still be close to the ideal of having reproducible builds.
