Picture map, filter, and fold as for loops with annotations that restrict what they can do. This helps both the source code reader (you and I) and the source code compiler more easily understand what's going on. For the compiler this m

For me the compile time and runtime distinctions are more important.

Go is more from the typed world than Python where I came from. It will tell you at compile time you are using a string rather than an int (unless you use interface{}).

One thing I can credit Go for is leading me from the untyped world to the typed one. I soon found the holes in the Go type system, and went looking for a stronger type system. I now generally prefer Haskell.

Go doesn't make real world programming easier. It makes you work hard for pointless things. Most of its problems are from a lack of generics.

by codygman 10y ago
As someone who writes Go every day for work, I can't agree that Go is simple. Using a language for analytics without generics can be quite painful and error prone. Go is a language that pushes remembering corner cases and failure condi

inshell "ls" would do what you are talking about, unless your bar for simple is just typing ls.

The authors encourages anyone that can't afford the book to contact them through their support link on the Haskellbook.com site to work something fair out.

I think it's the most used by non haskeller's. I'd say most used and most famous is the ghc Haskell compiler.

I'm not sure if Scala.js is production ready, but both Purescript and Elm have been used in production for a few years.

Can you give some examples of abstractions that leak which the community doesn't want (or hasn't wanted) to address?

> hindley-milner style type checking is nice, but once you admit that things like arrays exist How are these related? Haskell has arrays. Arrays can be represented as algebraic data types as well. What is it you think Haskell has trouble

I think the real magic here is you can drop down (fly up?) to writing Haskell code alongside this bash like DSL and have sane flow control.

This too was wrong and the real problem was me putting "monads-tf" in my build dependencies instead of "mtl". I got bit by using a macro on that list of "try adding X dependency". In any case, the original post

The actual solution isn't modifying the cabal file here at all, it is adding "extra-dep: true" to stack.yaml when we start using the cassandra-cql dependency from GitHub. I'll be updating the post again soon.

I only know of two somewhat comprehensive studies on this. One says Haskell had far fewer bugs and the other has a conclusion like yours. You make it sound like there are numerous studies supporting your conclusion, can you link a few of th
