      I'm fine with this suggestion. We considered it for F# 3.0 but cut it, since you can always implement this pattern in a more expanded form using "let" and explicit get/set.

      It won't be high priority for myself, but if some one does it, that is great

      Will mark this approved-in-principle (will show as "planned")

            This is approved for inclusion in a future release of F# subject to an implementation and detailed design. A pull request to implement this feature will be necessary and we encourage contributors to submit one with adequate design detail and testing to http://github.com/Microsoft/visualfsharp. Discussion of the particular version for this to be included in can be made once an implementation is available.

            Design detail can also be discussed below.

            This seems entirely reasonable for scripting code.

            I'll mark it as "approved in principle", however the Visual F# Tools team and others may have opinions about how we deal with this kind of configuration parameter. Probably the best thing to do is send a PR to http://github.com/Microsoft/visualfsharp and continue the discussion there, then link back to this discussion.

              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.

                  Updating to planned to indicate this is approved in general terms. A detailed design and implementation would be needed.

                  Implementations of approved language design 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 proposal is “approved in principle” for F# 4.0+. It would make a good addition to F#. (I don’t think the loss of purity (e.g. wr.t. ordering of union cases) is a critical problem and I believe you can turn of the DefaultAugmentation in any case)

                    Some technical issues may need to be ironed out during implementation.

                    If this is done, the Tag properties present on these types should also be revealed, that is covered by a separate item.

                    An implementation and testing would need to be provided by someone in the F# community (possibly including Microsoft or Microsoft Research, though not limited to them).

                    Implementations of approved language design 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..

                    I’d be glad to help guide people through the implementation process.
