In my current application, I'm really missing the ability from OO to do things like someData.field1.field2 = "foo" What's do I mean? - field selectors are scoped so that names don't clash with each other or global names - this way of selecting data can be used both for reading it, and for updating specific fields of some data deep in a data hierarchy (In Haskell, if using immutable data, this would requiring doing a data update on every level). Any attempt to do this in Haskell, for me anyway, results in an explosion of names and a lot of boilerplate code and a resulting heavy syntax. Is there a way of obtaining OO-like concise syntax, perhaps with Template Haskell? Dennis
