Re: [Haskell-cafe] what is basic Haskell?

I'm curious to know why you have included functional dependencies under basics. I'd call that an advanced concept, since a Haskell programmer could be effective even without understanding it. Although, if your company makes heavy use of these, then I suppose you ought to consider it basic for new recruits. Alex On 2014-07-24, at 7:01 PM, Wojciech Danilo wrote:

This is **very** interesting question! When we recruit people to our company (we are working in Haskell everyday), we are basing on some classification between basic, intermediate and advanced stuff. These sections are shown below. I would love to hear what others are thinking about it and what from the below stuff would be widely considered as "basic Haskell knowledge", which would allow for full-time basic Haskell work.

For my money, basic programming skills are those that are required to write programs for simple tasks in the common idioms of the language. This means the practitioner should be able to read input from the terminal or files, select/combine/reformat data, and output a result. At this point, efficiency isn't really the point; only getting to a correct answer without writing anything really weird matters.

In LYAH, I'd put the boundary at the end of chapter 9, which covers the IO monad. At that point the reader has studied functions, lists, tuples, types, recursion, higher order functions, four major modules, and algebraic data types. Actually, some of the later topics in chapter 8 (functors, kinds, recursive data structures) seem more like intermediate material.

Thoughts?
