New functions added to List, Array, Seq modules in F# 4.0 are missing Docs

[liboz]

Many new functions were added in F# 4.0: https://github.com/fsharp/FSharpLangDesign/blob/master/FSharp-4.0/ListSeqArrayAdditions.md. Most of them do not have documentation yet.

Here's the list of functions that still need docs:

Thanks for putting this table together @liboz!

[liboz]

@cartermp I plan on making at least some of the docs that are missing. Should I make multiple pull requests (something like one for each group of functions, i.e. List.contains, Array.contains, Seq.contains) or one big pull request or is there some other method that would be preferred?

[dend]

@liboz as soon as you have a new article, issue a PR. Unless you have 7 ready at once, one-by-one is fine and we'll make sure to review and merge them properly.

[eriawan]

@cartermp @dend I already create a PR #193 for this, especially for new APIs (functions) in the What's new in F# MD. Please review it guys :) If you are OK with this, don't merge it yet. I'll continue to do the doc writings.

[eriawan]

Maybe we could combine with the works from @liboz :)

Hi. Any progress? List.groupBy is missing documentation too at both https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/lists and https://msdn.microsoft.com/visualfsharpdocs/conceptual/collections.list-module-%5bfsharp%5d

[hickford]

List.allPairs is also missing documentation https://github.com/MicrosoftDocs/visualfsharpdocs/issues/310

[ScottHutchinson]

I will try to help with this, but it seems to me that the people who added the new functions should add the documentation too. They would know best exactly how the function works and how to use it, etc.

[hickford]

Looks like most or even all these functions are now documented at

• https://fsharp.github.io/fsharp-core-docs/reference/fsharp-collections-listmodule.html
• https://fsharp.github.io/fsharp-core-docs/reference/fsharp-collections-seqmodule.html
• https://fsharp.github.io/fsharp-core-docs/reference/fsharp-collections-arraymodule.html

@hickford That is only the bare minimum documentation generated from XML comments. There are no examples, for instance. That is inadequate.
