Yes, it's in utils/haddock in the main tree, and that really does need to be done before release. | One of the things that we ought to be able to do with this extension is | to provide abstract datatypes with pattern matching support. The only | thing missing is support for exhaustive pattern matches. F# active | patterns has it! We already lack exhaustiveness support as soon as we have guards or view patterns. But it seems a bit more feasible with pattern synonyms. Something to add to the "missing features" list!
