      Type aliases only would help a bit but not really solve the problem completely. Having local records and DUs would be much better

      Actually, even if members weren't allowed this would be already very useful. On local scope we usually use a lot of tuples, and refactoring to records or DUs is usefull, but it's a bit annoying that you have to do that at global scope

      (b) Should not be possible, as these types should be private to the function, so an error should be issued on that case

      (a) Yes, they should be full type definitions. Capturing values from scope would be an added bonus, but would be also ok if that wasn't supported, I guess.

                        Approved in principle for F# 4.0 (or later, depending), along with “allow type providers to report warnings”. subject to a suitable implementation being submitted. Both are entirely reasonable

                        Implementations of approved language design items can now be submitted as pull requests to the appropriate branch of http://github.com/Microsoft/visualfsharp. See http://fsharp.github.io/2014/06/18/fsharp-contributions.html for information on contributing to the F# language and core library.

                            This is approved-in-principle for F# 4.x+

                            A detailed design is needed. I would prefer one that is idiom-based and doesn’t force type providers to use a later FSharp.Core.dll

                            Implementations of approved language design items can now be submitted as pull requests to the appropriate branch of http://github.com/Microsoft/visualfsharp.

                            Maybe if the class that implements ITypeProvider has a public event named "WarningGenerated" or something like that, the compiler could plug into it and listen. It's a bit hack-y, but as there is a canonical implementation of ITypeProvider in TypeProviderForNameSpaces, we could create a method there called "EmitWarning", and hide how it's implemented, so there would not be a requirements for a specific FSharp.Core.
                            Unfortunately, I'm not remembering the case I was thinking about that I wanted to generate a warning on. I think it was in CsvProvider, but can't remember exactly
