Re: [Haskell-cafe] Re: Versioning

Hi

In other words, you can program in Haskell just fine without extensions. But if you want that "next level" in type safety, extensions is where it's at, at least for the kind of code I write.

What level of "safety" do these type extensions give you? The biggest runtime crasher is probably pattern match failings, something that most of these type extensions don't catch at all! They do give you some safety, but not a massive amount, and not in the places where it would be truely useful. Thanks Neil
