[Haskell-cafe] Derived Read for records

Someone at work just asked me about the inflexibility of the derived Read
instances for records -- specifically that they require fields to be given
in the same order as in the type definition and that fields cannot be
omitted. I hadn't been aware of these restrictions.

A few questions:

* Are there known work-arounds?
* Is it particularly difficult to synthesize more flexible Read instances?
* Do people just not mind the restrictions?
